A method of processing a plate-shaped workpiece includes a workpiece supporting step of placing the plate-shaped workpiece on a thermocompression sheet whose area is larger than that of the plate-shaped workpiece, heating the thermocompression sheet to pressure-bond the thermocompression sheet to the plate-shaped workpiece, and supporting the plate-shaped workpiece on only the thermocompression sheet, a processing step of processing the plate-shaped workpiece to divide the plate-shaped workpiece into a plurality of chips, and a pick-up step of picking up the chips from the thermocompression sheet.

A method of processing a plate-shaped workpiece includes a workpiece supporting step of placing a plate-shaped workpiece on an upper surface of a sheet whose area is larger than that of the plate-shaped workpiece through a liquid resin interposed therebetween and supporting the plate-shaped workpiece on only the liquid resin that has solidified and the sheet, a processing step of processing the plate-shaped workpiece to divide the plate-shaped workpiece into a plurality of chips, and a pick-up step of picking up the chips from the sheet.

A tape is stuck to the front surface of a workpiece in such a manner that the direction in which the stretch rate becomes the lowest when a predetermined force is applied to the tape is non-parallel to each of multiple planned dividing lines extending in a lattice manner. In this case, each of the multiple planned dividing lines does not extend along the direction perpendicular to this direction. This can reduce the ratio of the region to which the tape does not stick in the front surface of the workpiece in the vicinity of the boundary between each of the multiple planned dividing lines and a region in which a device is formed and suppress deterioration of the processing quality when the workpiece is divided from the back surface side by a cutting blade.

A chuck for a laser beam wafer dicing equipment includes a wafer support plate having an upper surface for holding a wafer disposed on a dicing tape. The upper surface includes a topographically structured surface region that partly or completely overlaps an edge of the wafer when the wafer disposed on the dicing tape is placed on the upper surface. The topographically structured surface region provides for a reduction in an area of contact between the upper surface and the dicing tape.

An apparatus for fabricating a display panel includes a fixing frame configured to secure an outer periphery of a first transfer film on which light emitting elements are arranged, a film mounting member on which the fixing frame is mounted, a stretching processing member configured to stretch the first transfer film by pressing a rear surface of the first transfer film in a forward direction, and a transfer processing member configured to transfer the light emitting elements to a support film or a second transfer film, the light emitting elements having an interval therebetween changed due to stretching of the first transfer film.

A method for transferring a plurality of die operatively associated with a transfer apparatus to a glass substrate to form a circuit component. The transfer occurs by positioning the glass substrate to face a first surface of a die carrier carrying multiple die. A reciprocating transfer member thrusts against a second surface of the die carrier to actuate the transfer member thereby causing a localized deflection of the die carrier in a direction of the surface of the glass substrate to position an initial die proximate to the glass substrate. The initial die transfers directly to a circuit trace on the glass substrate. At least one of the die carrier or the transfer member is then shifted such that the transfer member aligns with a subsequent die on the first surface of the die carrier. The acts of actuating, transferring, and shifting are repeated to effectuate a transfer of the multiple die onto the glass substrate.

A wafer dividing method of dividing a wafer along each of a plurality of projected dicing lines set in a grid pattern on a front surface of the wafer includes forming a division initiating point serving as an initiating point of division of the wafer along each of the dicing lines, adhering a protective film made of an olefin-based resin and having one surface with no adhesive used therein to the wafer in such a manner that the one surface is brought into intimate contact with the front surface of the wafer, supporting the wafer by a support table in such a manner that the front surface of the wafer and the support table face each other, and applying an external force to the wafer from a back surface side of the wafer to thereby divide the wafer at the division initiating points.

A micro device mass transfer equipment including a base stage, a moving stage, a substrate stage, a laser device, a rolling and pressing mechanism, and a heating mechanism is provided. The moving stage is movably disposed on the base stage, and moves with a moving path. The substrate stage is movably disposed on the base stage, and is adapted to move between different positions overlapping the moving stage. The laser device is movably disposed on the base stage. The laser device is adapted to move relative to the substrate stage, and emits a laser beam toward the substrate stage. The rolling and pressing mechanism is disposed on the moving path of the moving stage, and forms a contact region with the moving stage. The heating mechanism is disposed corresponding to the contact region, and is adapted to heat the contact region between the moving stage and the rolling and pressing mechanism.

A system for transfer of a plurality of die from a die source to a receive substrate is provided. The system includes a die source including a plurality of die, the plurality of die being coupled to a carrier. The system also includes a receive substrate to receive the plurality of die from the die source. The receive substrate includes a die catch material for receiving the plurality of die from the die source, the die catch material being reusable. The system also includes a laser source for providing energy to interact with a die release material to transfer the plurality of die from the die source to the receive substrate.
