(39) Hereafter, methods for manufacturing the sample storage device 200 as described above will be described in detail.

FIRST EMBODIMENT

(40) As shown in FIG. 4, a method for manufacturing a sample storage device in accordance with a first embodiment includes (a) preparing a pattern forming mold which has an engraved pattern part for forming at least the sidewall of a charging chamber, on the upper surface thereof; (b) pouring a predetermined amount of a liquid UV curable resin to be accommodated in the engraved pattern part, on the upper surface of the pattern forming mold; (c) seating a first light-transmitting substrate on the upper surface of the pattern forming mold and pressing them to each other; (d) radiating UV with the liquid UV curable resin accommodated in the engraved pattern part and thereby curing the liquid UV curable resin; (e) separating the first light-transmitting substrate which has the sidewall of the charging chamber formed as the liquid UV curable resin is cured, from the pattern forming mold; and (f) forming the charging chamber by adhering a second light-transmitting substrate to a surface of the first light-transmitting substrate on which the sidewall is formed.

(41) First, the step (a) will be described.

(42) The step (a) is the step of preparing a pattern forming mold 100 which has an engraved pattern part 104 for forming at least the sidewall 210a of the charging chamber s, on the upper surface thereof.

(43) The engraved pattern part 104 may be formed into various patterns to form various shapes which include the sidewall 210a of the charging chamber s, outside the charging chamber s.

(44) For example, as shown in FIGS. 8 and 9, the engraved pattern part 104 may be formed to include a sidewall pattern 104a which is formed through engraving to form the sidewall 210a of the charging chamber s, and a plurality of line patterns 104b which are spaced apart from one another by a predetermined interval outside the sidewall pattern 104a and are formed through engraving to form the plurality of line walls 210b outside the sidewall 210a of the charging chamber s.

(45) Also, the engraved pattern part 104 may be formed by only the sidewall pattern 104a without the line patterns 104b, or may be formed in such a manner that the width of the sidewall 210a of the charging chamber s is increased by forming the entirety of the region remaining by excluding a region for forming the charging chamber s, through engraving. That is to say, the engraved pattern part 104 may be variously changed in its shape.

(46) Meanwhile, as shown in FIGS. 16 and 17, the engraved pattern part 104 may be formed to include a grid pattern 104c for forming grid scales 200g, at a region inside the sidewall pattern 104a.

(47) The grid pattern 104c may be formed through embossing or engraving at portions corresponding to the scale line portions of the grid scales 200g.

(48) As shown in FIGS. 7a and 7b, the engraved pattern part 104 may be constructed by an electroformed mold 104 which has a pattern for forming the sidewall 210a of the charging chamber s. As the electroformed mold 104 is fixed to the upper surface of a pattern forming mold base 102, the pattern forming mold 100 may be constructed.

(49) In other words, as shown in FIG. 7a, by defining a fixing groove 102h in which the electroformed mold 104 may be fixed, on the upper surface of the pattern forming mold base 102 and by inserting and fixing the electroformed mold 104 in the fixing groove 102h, the pattern forming mold 100 as shown in FIG. 7b may be constructed.

(50) An electroformed mold refers to a mold which is fabricated by an electroforming method. Electroforming is a method of forming a metal layer to a predetermined thickness on the surface of a master fabricated through machining, by using electroplating, separating the formed metal layer, and forming the separated metal layer as a mold through finishing.

(51) For example, an electroformed mold of a predetermined thickness may be fabricated by placing a metallic material for forming a mold and a master in a nickel sulfate aqueous solution in the same manner as in a plating method and connecting the metallic material with a positive electrode and the master with a negative electrode, to cause the metal particles of the metallic material connected to the positive electrode to migrate and cling to the surface of the master.

(52) In the electroformed mold 104 as described above, since a mold may be formed to have a fine shape, it is easy to form the sidewall 210a of the charging chamber s which has a height and a thickness of a micro unit.

(53) The electroformed mold 104 may be formed to include a grid pattern 104c for forming grid scales 200g, at a region inside the sidewall pattern 104a for forming the sidewall 210a of the charging chamber s.

(54) Namely, the electroformed mold 104 may be formed to include all of the sidewall pattern 104a, the line patterns 104b and the grid pattern 104c.

(55) Meanwhile, as shown in FIG. 9, the engraved pattern part 104 may be constructed as patterns for forming the sidewall 210a and the line walls 210b of the charging chamber s are etched on the upper surface of the pattern forming mold base 102.

(56) The patterns may be formed through etching generally known in the art. For example, patterns for forming the sidewall 210a and the line walls 210b may be formed on the upper surface of the pattern forming mold base 102, by forming an oxide film on the upper surface of the pattern forming mold base 102, depositing a photosensitive resin on the oxide film, photosensitizing the photosensitive resin by radiating UV through a negative type mask, removing the photosensitized photosensitive resin, removing the oxide film at positions where the photosensitive resin is removed, removing the left photosensitive resin, and impregnating impurity gases at the positions where the oxide film does not exist.

(57) The pattern forming mold 100 fabricated through etch-processing may be provided with a grid scale forming electroformed mold 105 for forming grid scales 200g, at a region inside the sidewall pattern 104a for forming the sidewall 210a of the charging chamber s.

(58) The grid scales 200g formed at a region inside the sidewall 210a of the charging chamber s are formed to have a shape more fine than the sidewall 210a or the line walls 210b of the charging chamber s, and thus, it may be difficult to form patterns for forming the grid scales 200g, through etch-processing.

(59) Therefore, after fabricating the grid scale forming electroformed mold 105 for forming the grid scales 200g, by an electroforming method capable of forming fine patterns, a groove 105h is defined at the region inside the sidewall pattern 104a of the etch-processed pattern forming mold 100, and the grid scale forming electroformed mold 105 is inserted into the groove 105h, by which the pattern forming mold 100 is constructed.

(60) As described above, the engraved pattern part 104 may be formed on the upper surface of the pattern forming mold base 102 by fixing the electroformed mold 104 having the pattern for forming the sidewall 210a of the charging chamber s, to the upper surface of the pattern forming mold base 102, or by etch-processing the pattern for forming the sidewall 210a of the charging chamber s, on the upper surface of the pattern forming mold base 102, and through this, the pattern forming mold 100 may be prepared.

(61) The step (b) will be described.

(62) The step (b) is the step of pouring the predetermined amount of the liquid UV curable resin RS to be accommodated in the engraved pattern part 104, on the upper surface of the pattern forming mold 100.

(63) For example, as shown in FIG. 10a, the predetermined amount of the liquid UV curable resin RS capable of being entirely accommodated in the engraved pattern part 104 may be poured at one end of the engraved pattern part 104 on the upper surface of the pattern forming mold 100.

(64) For another example, as shown in FIG. 10b, the liquid UV curable resin RS may be poured entirely on the upper surface of the pattern forming mold 100, in detail, entirely on the engraved pattern part 104, such that the liquid UV curable resin RS may be applied entirely to the engraved pattern part 104.

(65) The liquid UV curable resin RS is a resin for forming the sidewall 210a and the line walls 210b of the charging chamber s. For example, as a urethane acrylate-based liquid UV curable resin generally known in the art, ND-938 of NANO PHOTONICS CHEMICAL CO., LTD may be used.

(66) In order to increase the curability of the liquid UV curable resin RS, the liquid UV curable resin RS may be used by being mixed with a curing agent.

(67) The step (c) will be described.

(68) The step (c) is the step of seating the first light-transmitting substrate 210 on the upper surface of the pattern forming mold 100 and pressing them to each other.

(69) For example, as shown in FIGS. 11 and 12, in the state in which the predetermined amount of the liquid UV curable resin RS is poured at one end of the engraved pattern part 104 on the upper surface of the pattern forming mold 100, the first light-transmitting substrate 210 may be aligned with and seated on the upper surface of the pattern forming mold 100.

(70) The pressing of the pattern forming mold 100 and the first light-transmitting substrate 210 to each other may be carried out by the deadweight of the first light-transmitting substrate 210 or by separate pressing means.

(71) For example, as shown in FIG. 13, the pattern forming mold 100 and the first light-transmitting substrate 210 may be pressed to each other as they pass through between a pair of pressing rollers R from the end of the engraved pattern part 104 where the liquid UV curable resin RS is poured.

(72) Besides, other pressing means known in the art may be optionally applied so long as it is possible to press the pattern forming mold 100 and the first light-transmitting substrate 210 to each other.

(73) Through the above-described pressing process, the liquid UV curable resin RS may exist in the form of a film with a thickness of approximately 3 m between the embossed portions of the engraved pattern part 104 of the pattern forming mold 100 and the first light-transmitting substrate 210, and the liquid UV curable resin RS is filled in correspondence to the engraved patterns between the engraved portions of the engraved pattern part 104 of the pattern forming mold 100 and the first light-transmitting substrate 210.

(74) The height of the engraved portions may be set to approximately 10 m to 100 m as the height of the charging chamber s.

(75) The step (d) will be described.

(76) The step (d) is the step of radiating UV with the liquid UV curable resin RS accommodated in the engraved pattern part 104 and thereby curing the liquid UV curable resin RS.

(77) That is to say, the step (d) may be performed after the pattern forming mold 100 and the first light-transmitting substrate 210 pass through the pair of pressing rollers R.

(78) For example, as shown in FIG. 13, as the pattern forming mold 100 and the first light-transmitting substrate 210 pass through the pair of pressing rollers R from the end of the engraved pattern part 104 where the liquid UV curable resin RS is poured, the liquid UV curable resin RS may be evenly distributed wholly between the pattern forming mold 100 and the first light-transmitting substrate 210 and may be accommodated in the engraved pattern part 104.

(79) As UV is radiated toward a discharge side through which the pattern forming mold 100 and the first light-transmitting substrate 210 pass through the pair of pressing rollers R and are then discharged, the liquid UV curable resin RS evenly distributed between the pattern forming mold 100 and the first light-transmitting substrate 210 may be cured.

(80) The step (e) will be described.

(81) The step (e) is the step of separating the first light-transmitting substrate 210 which has the sidewall 210a formed as the liquid UV curable resin RS is cured, from the pattern forming mold 100.

(82) The pattern forming mold 100 may be release-processed such that the cured resin may be easily released. For example, the pattern forming mold 100 may be release-processed through annealing, plating, deposition coating, etc.

(83) Therefore, the first light-transmitting substrate 210 having the sidewall 210a which is formed as the liquid UV curable resin RS is cured may be easily separated from the pattern forming mold 100.

(84) The step (f) will be described.

(85) The step (f) is the step of forming the charging chamber s by adhering the second light-transmitting substrate 220 to the surface of the first light-transmitting substrate 210 on which the sidewall 210a is formed.

(86) As shown in FIG. 14, the second light-transmitting substrate 220 is formed to have substantially the same area as the first light-transmitting substrate 210, and is formed with the introducing part 220a for charging a sample into the charging chamber s and the discharging part 220b for discharging the sample or air.

(87) The first light-transmitting substrate 210 and the second light-transmitting substrate 220 may be adhered to each other by stacking them through applying a UV curable adhesive between them excluding a region corresponding to the charging chamber s and then radiating UV.

(88) For example, the UV curable adhesive may be applied to be filled in the spaces between some line walls 210b. When adhering the first light-transmitting substrate 210 and the second light-transmitting substrate 220, as the UV curable adhesive filled in the spaces between some line walls 210b flows into the spaces between neighboring line walls 210b and is thus evenly distributed wholly, it is possible to prevent the UV curable adhesive from leaking to an outside through the pair of substrates.

(89) The UV curable adhesive as a liquid substance including, for example, urethane acrylate, is generally referred to as liquid UV, and has a characteristic that it is cured when heat is applied or UV is radiated.

(90) In order to increase the curability of the liquid UV curable adhesive, the liquid UV curable adhesive may be used by being mixed with a curing agent.

(91) As the first light-transmitting substrate 210 and the second light-transmitting substrate 220 are adhered as described above, as shown in FIG. 15, the sample storage device 200 having the charging chamber s may be completed.

SECOND EMBODIMENT

(92) As shown in FIG. 5, a method for manufacturing a sample storage device in accordance with a second embodiment includes (a) preparing a pattern forming mold which has an engraved pattern part for forming at least the sidewall of a charging chamber, on the upper surface thereof, the engraved pattern part being formed such that a plurality of pattern parts each of which forms the sidewall of a single charging chamber are arranged therein and thereby form the sidewalls of a plurality of charging chambers; (b) pouring a predetermined amount of a liquid UV curable resin to be accommodated in the engraved pattern part, on the upper surface of the pattern forming mold; (c) seating a first light-transmitting base substrate on the upper surface of the pattern forming mold and pressing them to each other; (d) radiating UV with the liquid UV curable resin accommodated in the engraved pattern part and thereby curing the liquid UV curable resin; (e) separating the first light-transmitting base substrate which has the sidewalls of the plurality of charging chambers formed as the liquid UV curable resin is cured, from the pattern forming mold; (f) cutting the first light-transmitting base substrate such that the sidewalls of the plurality of charging chambers are divided into the individual sidewalls of individual charging chambers and thereby defining first light-transmitting substrates; and (g) forming each charging chamber by adhering a second light-transmitting substrate to a surface of each first light-transmitting substrate on which the sidewall is formed.

(93) First, the step (a) will be described.

(94) The step (a) is the step of preparing a pattern forming mold 100 which has an engraved pattern part 104 for forming at least the sidewall 210a of the charging chamber s, on the upper surface thereof, and the engraved pattern part 104 is formed such that a plurality of pattern parts 104 each of which forms the sidewall 210a of a single charging chamber s are arranged therein and thereby form the sidewalls 210a of a plurality of charging chambers s.

(95) For example, as shown in FIGS. 18a, 18b and 19, the engraved pattern part 104 may be formed such that the pattern parts 104 each of which forms the sidewall 210a of a single charging chamber s are arranged in the form of 210. Each pattern part 104 forms the sidewall 210a of the charging chamber s of one sample storage device.

(96) In other words, the engraved pattern part 104 according to the second embodiment is constructed in such a manner that the plurality of pattern parts 104 are arranged to be capable of simultaneously forming the sidewalls 210a of the charging chambers s of a plurality of sample storage devices. Since a plurality of sample storage devices may be manufactured through one time manufacturing process by using such an engraved pattern part 104, mass production is made possible.

(97) The pattern parts 104 which form the engraved pattern part 104 may be formed into various patterns to form various shapes outside the charging chambers s including the sidewalls 210a of the charging chambers s.

(98) For example, as shown in FIGS. 18a, 18b and 19, each of the pattern parts 104 may be formed to include a sidewall pattern 104a, line patterns 104b and a grid pattern (not shown). Since the detailed pattern shapes are the same as or similar to the shapes of the sidewall pattern 104a, the line patterns 104b and the grid pattern 104c of the engraved pattern part 104 according to the first embodiment, repeated descriptions thereof will be omitted herein.

(99) Also, similarly to the engraved pattern part 104 according to the first embodiment, in the case of the engraved pattern part 104 according to the second embodiment, for example, as shown in FIGS. 18a and 18b, the pattern forming mold 100 may be constructed by disposing an electroformed mold 104 on the upper surface of a pattern forming mold base 102, or, as shown in FIG. 19, the pattern forming mold 100 may be constructed by forming patterns on the upper surface of a pattern forming mold base 102 through etch-processing. Repeated descriptions thereof will be omitted.

(100) The step (b) will be described.

(101) The step (b) is the step of pouring the predetermined amount of the liquid UV curable resin RS to be accommodated in the engraved pattern part 104, on the upper surface of the pattern forming mold 100.

(102) For example as shown in FIG. 20a, the predetermined amount of the liquid UV curable resin RS capable of being entirely accommodated in the engraved pattern part 104 may be poured at one end of the engraved pattern part 104 on the upper surface of the pattern forming mold 100, or, as shown in FIG. 20b, the liquid UV curable resin RS may be poured entirely on the upper surface of the pattern forming mold 100, in detail, entirely on the engraved pattern part 104, such that the liquid UV curable resin RS may be applied entirely to the engraved pattern part 104.

(103) The liquid UV curable resin RS is a resin for forming the sidewall 210a and the line walls 210b of the charging chamber s. For example, as a urethane acrylate-based liquid UV curable resin generally known in the art, ND-938 of NANO PHOTONICS CHEMICAL CO., LTD may be used.

(104) The step (c) will be described.

(105) The step (c) is the step of seating a first light-transmitting base substrate 210 on the upper surface of the pattern forming mold 100 and pressing them to each other.

(106) For example, as shown in FIGS. 21 and 22, in the state in which the predetermined amount of the liquid UV curable resin RS is poured at one end of the engraved pattern part 104 on the upper surface of the pattern forming mold 100, the first light-transmitting base substrate 210 may be aligned with and seated on the upper surface of the pattern forming mold 100.

(107) For example, as shown in FIG. 23, the pressing of the pattern forming mold 100 and the first light-transmitting base substrate 210 to each other may be carried out as they pass through between a pair of pressing rollers R from the end of the engraved pattern part 104 where the liquid UV curable resin RS is poured.

(108) Besides, other pressing means known in the art may be optionally applied so long as it is possible to press the pattern forming mold 100 and the first light-transmitting base substrate 210 to each other.

(109) Through the above-described pressing process, the liquid UV curable resin RS may exist in the form of a film with a thickness of approximately 3 m between the embossed portions of the engraved pattern part 104 of the pattern forming mold 100 and the first light-transmitting base substrate 210, and the liquid UV curable resin RS is filled in correspondence to the engraved patterns between the engraved portions of the engraved pattern part 104 of the pattern forming mold 100 and the first light-transmitting base substrate 210.

(110) The height of the engraved portions may be set to approximately 10 m to 100 m as the height of the charging chamber s.

(111) The step (d) will be described.

(112) The step (d) is the step of radiating UV with the liquid UV curable resin RS accommodated in the engraved pattern part 104 and thereby curing the liquid UV curable resin RS.

(113) That is to say, the step (d) may be performed after the pattern forming mold 100 and the first light-transmitting base substrate 210 pass through the pair of pressing rollers R.

(114) For example, as shown in FIG. 23, as the pattern forming mold 100 and the first light-transmitting base substrate 210 pass through the pair of pressing rollers R from the end of the engraved pattern part 104 where the liquid UV curable resin RS is poured, the liquid UV curable resin RS may be evenly distributed wholly between the pattern forming mold 100 and the first light-transmitting base substrate 210 and may be accommodated in the engraved pattern part 104.

(115) As UV is radiated toward a discharge side through which the pattern forming mold 100 and the first light-transmitting base substrate 210 pass through the pair of pressing rollers R and are then discharged, the liquid UV curable resin RS evenly distributed between the pattern forming mold 100 and the first light-transmitting base substrate 210 may be cured.

(116) The step (e) will be described.

(117) The step (e) is the step of separating the first light-transmitting base substrate 210 which has the sidewalls 210a of the plurality of charging chambers s formed as the liquid UV curable resin RS is cured, from the pattern forming mold 100.

(118) The pattern forming mold 100 may be release-processed such that the cured resin may be easily released. For example, the pattern forming mold 100 may be release-processed through annealing, plating, deposition coating, etc.

(119) Therefore, the first light-transmitting base substrate 210 having the sidewalls 210a which are formed as the liquid UV curable resin RS is cured may be easily separated from the pattern forming mold 100.

(120) The step (f) will be described.

(121) The step (f) is the step of cutting the first light-transmitting base substrate 210 such that the sidewalls 210a of the plurality of charging chambers s are divided into the individual sidewalls 210a of individual charging chambers s and thereby defining first light-transmitting substrates 210.

(122) For example, as shown in FIG. 24, on one surface of the first light-transmitting base substrate 210 which is formed through the above steps (a) to (e), the sidewalls 210a and the line walls 210b which form the individual charging chambers s are arranged in the form of 210.

(123) By cutting the first light-transmitting base substrate 210 along imaginary cutting lines c, the first light-transmitting substrates 210 are defined.

(124) The cutting of the first light-transmitting base substrate 210 may be carried out in a mechanical cutting scheme such as Thomson cutting, NC cutting, etc.

(125) Therefore, similarly to the first light-transmitting substrate 210 according to the first embodiment shown in FIG. 14, on one surface of each of the first light-transmitting substrates 210 which are formed as the first light-transmitting base substrate 210 is cut, one sidewall 210a and the plurality of line walls 210b which form one charging chamber s may be provided.

(126) The step (g) will be described.

(127) The step (g) is the step of forming the charging chamber s by adhering the second light-transmitting substrate 220 to the surface of the first light-transmitting substrate 210 on which the sidewall 210a is formed.

(128) The second light-transmitting substrate 220 (see FIG. 14) is formed to have substantially the same area as the first light-transmitting substrate 210, and is formed with the introducing part 220a for charging a sample into the charging chamber s and the discharging part 220b for discharging the sample or air.

(129) The first light-transmitting substrate 210 and the second light-transmitting substrate 220 may be adhered to each other by stacking them through applying a UV curable adhesive between them excluding a region corresponding to the charging chamber s and then radiating UV. Since a detailed adhering method is the same as in the first embodiment, repeated descriptions will be omitted herein.

(130) As the first light-transmitting substrate 210 and the second light-transmitting substrate 220 are adhered as described above, as in the sample storage device according to the first embodiment shown in FIG. 15, a single sample storage device may be completed.

(133) First, the step (f) will be described.

(134) The step (f) is the step of forming the plurality of charging chambers s by adhering a second light-transmitting base substrate 220 (see FIG. 26) to a surface of the first light-transmitting base substrate 210 (see FIG. 25) on which the sidewalls 210a of the plurality of charging chambers s are formed.

(135) As shown in FIG. 26, the second light-transmitting base substrate 220 is formed to have substantially the same area as the first light-transmitting base substrate 210, and is formed with a plurality of introducing parts 220a for charging samples into the respective charging chambers s and a plurality of discharging parts 220b for discharging the samples or air.

(136) The first light-transmitting base substrate 210 and the second light-transmitting base substrate 220 may be adhered to each other by stacking them through applying a UV curable adhesive between them excluding regions corresponding to the charging chambers s and then radiating UV.

(137) The step (g) will be described.
