DETAILED DESCRIPTION OF THE DRAWINGS

[0025] FIG. 1 illustrates a cross-sectional view of a packaged electronic device 10 in accordance with a first embodiment having electronic components 12, 14, 16, and 17 connected to a substrate 11. FIG. 1 is taken along reference line 1-1 of FIG. 2, which illustrates a top plan view of packaged electronic device 10. As illustrated in FIG. 2, packaged electronic device 10 further includes electronic components 18 and 19. FIGS. 1 and 2 illustrate an example of an electronic device structure having 3-axis directional capability.

[0026] In accordance with the present embodiment, electronic components 12 and 18 are provided as on-edge components 12 and 18 or as electronic components having a non-parallel orientation with respect to major surface 110 of substrate 11. In some embodiments, electronic component 12 and electronic component 18 can be provided with a generally orthogonal orientation with respect to major surface 110 of substrate 11. In one embodiment, electronic components 12, 14, 16, 17, 18, and 19 can be configured as antenna devices disposed on substrate 11 to provide 3-axis coverage. In some examples, one or more of electronic components 12, 14, 16, 17, 18, and 19 comprise semiconductor die, either packaged or unpackaged (i.e., bare semiconductor die). In other examples, one or more of electronic components 12, 14, 16, 17, 18 and 19 comprise passive components. By way of example, electronic components 12 and 17 are oriented to send and receive signals 120 along an x-axis of FIGS. 1 and 2; electronic components 14 and 16 are oriented to send and receive signals 121 along a z-axis of FIG. 1; and electronic components 18 and 19 are oriented to send and receive signals 122 along a y-axis of FIG. 2.

[0027] It is understood that other electronic components can be placed on substrate 11, but are not illustrated here so as to not crowd the figures. The other components can include integrated circuit devices, such as digital signal processing (DSP) devices, microprocessors, memory devices, microcontroller devices, power devices, passive devices, or other devices known to those skilled in the art. It is further understood that one or more of electronic components 12, 14, 16, 17, 18, and 19 can be other types of electronic devices, such as sensor devices (for example, CMOS or CCD image sensors), optical devices, or other devices known to those skilled in the art. Those skilled in the art will appreciate that the electronic components are illustrated in simplified form, and may further include multiple diffused regions, multiple conductive layers, and multiple dielectric layers.

[0028] Substrate 11 can be any kind of electronic component substrate, such as a printed circuit board (PCB), a build-up substrate, a laminate substrate, a leadframe substrate, a ceramic substrate, a molded substrate, a molded leadframe, or other substrates known to those skilled in the art. In one embodiment, substrate 11 is provided with a conductive pattern 21 adjacent to major surface 110 and a conductive pattern 22 adjacent to a major surface 111 opposite to major surface 110. Conductive patterns 21 and 22 can comprise conductive pads, conductive traces, or combinations thereof. In most embodiments, conductive patterns 21 and 22 comprise one or metal materials, such as copper, copper alloys, plated materials, gold, nickel gold, or other materials known to those skilled the art.

[0029] Substrate 11 can further include embedded traces and conductive interconnect vias (not shown) that electrically connect specific portions of conductive pattern 21 to other portions of conductive pattern 21, to conductive pattern 22, or to conductive bumps 23 provided adjacent major surface 111 of substrate 11. By way of example, conductive bumps 23 comprise temperature reflowable solder bumps, thermosonic or thermocompression bonded bumps (e.g., gold bumps), adhesively bonded bumps, or other bump materials known to those skilled in the art. Conductive bumps 23 are configured for attaching or electrically connected packaged electronic device 10 to a next level of assembly.

[0030] In some embodiments, electronic component 14 is attached to conductive pattern 21 with conductive bumps 31 and electronic component 16 is similarly attached to conductive pattern 22 with conductive bumps 31. Conductive bumps 31 can comprise temperature reflowable solder bumps, thermosonic or thermocompression bonded bumps (e.g., gold bumps), adhesively bonded bumps, or other bump materials known to those skilled in the art.

[0031] In accordance with the present embodiment, electronic component 12 is attached at an edge 126 to conductive pattern 21 using one or more conductive bumps 32 and solder 33. In some embodiments, edge 126 only partially overlaps conductive pattern 21 with conductive bumps 32 and solder 33 overlapping conductive pattern 21. An opposite edge 127 is disposed distal to major surface 110 of substrate 11. Electronic component 17 is attached at an edge 176 to conductive pattern 21 using one or more conductive bumps 32 and solder 33. An opposite edge 177 is disposed distal to major surface 110 of substrate 11. By way of example, conductive bumps 32 comprise lead-free solder balls or bumps (for example, tin (Sn) silver (Ag)). In accordance with the present embodiment, and as will be explained in more detail with FIGS. 3 and 5, during a reflow process that attaches or bonds electronic components 12, 14, 16, 17, 18 and 19 to substrate 11, a surface tension effect from the melted or softened solder and the conductive bumps is utilized to raise-up or pull-up electronic components 12, 17, 18 and 19 into an upright or non-parallel orientation with respect to major surface 110 of substrate 11. Stated a different way, after the reflow process, electronic components 12, 17, 18, and 19 are disposed on substrate 11 in an on-edge configuration such that the major surfaces of these components are other than generally parallel with major surface 110 of substrate 11. In one embodiment, an underfill layer 34 can be disposed adjacent to edges of electronic components 12, 17, 18, and 19 proximate to major surface 110 of substrate 11 to provide additional support or protection for electronic components 12, 17, 18, and 19 after electronic components 12, 17, 18, and 19 are placed in a desired upright orientation. Although not illustrated in the present example, underfill layers can also be used under electronic components 14 and 16. Solder 33 can be a lead-free solder, such as tin (Sn) silver (Ag) solder, and can be provided as a solder paste. In accordance with the present embodiment, electronic components 12, 17, 18, and 19 are attached at only one edge to substrate 11. In some examples, one or more of solder 33 and conductive bumps can be referred to as conductive material. As illustrated in FIG. 1, electronic component 12 has a major surface 125 that faces an edge 112 of substrate 11, and electronic component 17 has a major surface 175 that faces an edge 113 of substrate. It is understood that electronic components 18 and 19 also have major surfaces that face other edges 118 and 116 of substrate 11 as illustrated in FIG. 2.

[0032] In some embodiments, a package body 36 encapsulates or covers electronic components 12, 14, 17, 18, and 19. In some embodiments, package body 36 can be a polymer based composite material, such as an epoxy resin with filler, epoxy acrylate with filler, or polymer with proper filler. Package body 36 comprises a non-conductive and environmentally protective material that protects electronic components 12, 14, 17, 18, and 19 from external elements and contaminants. Package body 36 may be formed using paste printing, compressive molding, transfer molding, over-molding, liquid encapsulant molding, vacuum lamination, other suitable applicator, or other processes as known to those of skill in the art. In some embodiments, package body 36 is an epoxy mold compound (“EMC”), and can be formed using transfer or injection molding techniques. In other embodiments, another package body (not shown) may be used to encapsulate electronic component 16 disposed adjacent major surface 111 of substrate 11. In other embodiments, package body 36 may comprise a cap, lid, or other cover structures known to those skilled in the art. In other embodiments, package body 36 is not used.

[0033] With reference now to FIG. 2, examples of attachment schemes will be described. In one embodiment, only one side or one edge 126 of electronic component 12 is attached to individual conductive pads 21A to 21F using conductive bumps 32A to 32F and solder layer 33 or solder layers 33. In one embodiment, only one side or one edge 176 of electronic component 17 is attached to individual pads 21G to 21L using conductive bumps 32G to 32L and solder layer 33 or solder layers 33 (examples of solder layers 33 are illustrated in FIG. 1). In some embodiments, it is preferred that the conductive pads 21A to 21F are substantially equally distributed along edge 126 of electronic component 12 and that conductive pads 21G to 21L are substantially equally distributed along edge 176 of electronic component 17. As illustrated in FIG. 2, conductive pads 21A to 21F and conductive bumps 32A to 32F are disposed between an outer edge 115 of substrate 11 and electronic component 12. That is, an active surface of electronic component 12 is adjacent to or proximate to conductive bumps 32A to 32F. As is further illustrated in FIG. 2, conductive pads 21G to 21L and conductive bumps 32G to 32L are disposed between an outer edge 117 of substrate 11 and electronic component 17. That is, an active surface of electronic component 17 is adjacent to or proximate to conductive bumps 32G to 32L.

[0034] In one embodiment, only one side or edge 186 of electronic component 18 is attached to individual conductive pads 21M to 21P using conductive bumps 32M to 32W and solder layer 33 or solder layers 33. In the present embodiment, at least some of conductive pads 21M to 21P accommodate more than one conductive bump 32M to 32W. In some embodiments, it is preferred that conductive pads 21M to 21P are substantially equally distributed along a lower edge 186 of electronic component 18. As illustrated in FIG. 2, electronic component 18 is disposed between an outer edge 116 of substrate 11 and conductive pads 21M to 21P and conductive bumps 32M to 32W. That is, in one embodiment, an active surface of electronic component 18 is opposite to conductive bumps 32M to 32W.

[0035] In one embodiment, only one side or edge 196 of electronic component 19 is attached to individual conductive pads 21Q to 21T using conductive bumps 32X to 32AF and solder layer 33 or solder layers 33. In the present embodiment, at least some of conductive pads 21Q to 21T accommodate more than one conductive bump 32X to 32AF. In some embodiments, it is preferred that conductive pads 21Q to 21T are substantially equally distributed along a lower edge 196 of electronic component 19. As illustrated in FIG. 2, electronic component 19 is disposed between an outer edge 118 of substrate 11 and conductive pads 21Q to 21T and conductive bumps 32X to 32AF. That is, in one embodiment, an active surface of electronic component 18 is opposite to conductive bumps 32X to 32AF.

[0036] It is understood that the number of conductive pads and solder bumps are determined by the electrical I/O requirements of the electronic components and the cumulative volume of material needed to raise the electronic component into a desired upright position. It if further understood that some of the conductive pads and solder bumps may not provide electrical connectivity, but instead may be used to provide the surface tension effect of the present disclosure to attach the electronic component(s) to the substrate.

[0037] FIG. 3 illustrates a partial cross-sectional view of an example electronic device 30 in accordance with an embodiment at an early step of fabrication. In the present example, electronic component 12 includes a conductive pattern 128 disposed on an upward facing major surface 129, and is disposed with edge 126 adjoining conductive pattern 21 on substrate 11. In the present embodiment, a major surface 131 of electronic component 12 faces major surface 110 of substrate 11, but is spaced apart from major surface 110 to provide a gap 113. Conductive bump 32 is disposed adjacent to major surface 129 of electronic component 12, and solder layer 33 is disposed on conductive pattern 21 and contacts edge 126 and solder bump 32. In the present embodiment, major surface 129 can be the active surface of electronic component 12, which is on the same side as conductive bump 32. In accordance with the present embodiment, edge 127 of electronic component 12, which is opposite to edge 126, is provided absent any conductive bumps 32. Stated a different way, conductive bumps 32 are disposed only along or next to edge 126 of electronic component 12.

[0038] FIG. 4 is a top plan view of electronic component 12 in accordance with an example preferred embodiment. More particularly, electronic component 12 preferably has a width 1200 to height 1201 ratio or aspect ratio greater than one (1), such a width to height ratio of about five (5) to one (1) with a standard thickness in range from about 100 microns to about 200 microns. This aspect ratio is preferred to facilitate raising electronic component 12 to an elevated position, such as an upright position, in a subsequent fabrication step, such as a solder reflow process. Further, in accordance with the present embodiment, the width to height ratio of electronic component 12 can be used to determine the number and size of conductive bumps and the volume of solder 33 to use in order to raise electronic component 12 to a desired position during the solder reflow process.

[0039] FIG. 5 illustrates a partial cross-sectional view of electronic device 30 of FIG. 3 at a later step in fabrication within a manufacturing apparatus 50 in accordance with one embodiment. By way of example, manufacturing apparatus 50 can be a reflow furnace having a chamber 500, a support structure 501, and a heat source 502. In accordance with the present embodiment, during the reflow process, surface tension forces act to move electronic component 12 to a raised orientation, such as an upright orientation. More particularly, adhesion forces between solder 33, conductive bump 31 and electronic component 12 create a moment 504 of the surface tension force that rotates electronic component 12 about edge 126 thereby raising electronic component 12 to an upright position. In accordance with the present embodiment, moment 504 results because opposing edge 127 of electronic component 12 is not attached to substrate 11 during the reflow process. In one embodiment, electronic component 12 has a generally orthogonal orientation with respect to major surface 110 of substrate 11. By way of example, electronic device 30 may be exposed to a temperature in a range of about 220 degrees Celsius to about 250 degrees Celsius for about 30 to 90 seconds when lead-free solder materials are used.

[0040] FIG. 6 is a flow chart for manufacturing a packaged electronic device in accordance with an embodiment of the present description. In a step 601, an electronic component configured for a non-parallel orientation with respect to a substrate is provided. By way of example, the electronic component can be an antenna device, a sensor device, or an optical device. In some embodiments, the electronic component can be electronic components 12 or 18 as illustrated in FIGS. 1-3, or any of the electronic components illustrated in FIGS. 7-13 hereinafter. In some preferred embodiments, the electronic component has a width to height ratio of about 5 to 1. In some embodiments, the electronic component is provided with conductive bumps, such as conductive bumps 32, disposed on surface of the electronic component proximate to an edge of the electronic component along its width dimension.

[0041] In a step 602, a substrate for supporting the electronic component is provided. By way of example, the substrate can be a PCB substrate, build-up substrate, a laminate substrate, a leadframe substrate, a ceramic substrate, a molded substrate, a molded leadframe, or other substrates known to those skilled in the art. In some embodiments, the substrate can be substrate 11 provided with conductive patterns 21 and 22 for receiving one or more electronic components.

[0042] In a step 603, the electronic component is attached to the substrate using a solder material. By way of example, a pick-and-place apparatus may be used to place the electronic components in desired locations on the substrate. In some embodiments, solder material 33 is used to preliminarily attach the electronic device along only the edge having conductive bumps 32. That is, the edge opposite the edge having conductive bumps 32 is not attached to the substrate. By way of example, the solder materials can be first dispensed in desired amounts on desired locations on the conductive patterns before the electronic components are placed onto the substrate. A dispensing or screen printing process can be used to provide the solder materials on desired locations of the substrate. In some embodiments, the solder material at least partially covers respective portions of conductive pattern 21 where the electronic component is attached to the substrate. By way of example, the solder material can comprise a SnAg or other lead-free solders, may include a flux material, and may be provided as a solder paste. In step 603, other electronic components may be attached to the substrate in conventional configurations. Such other components can be integrated circuit devices, such as DSP devices, microprocessors, memory devices, microcontroller devices, power devices, passive devices, or other devices known to those skilled in the art.

[0043] In a step 604, the substrate and electronic components are exposed to an elevated temperature to reflow the conductive bumps and solder materials to permanently attach the electronic components to the substrate. In accordance with the present embodiment, at least one electronic component is raised to an elevated position during step 604 so that it is finally attached to the substrate in a non-parallel orientation to the substrate. By way of example, this can be electronic component 12 illustrated in FIGS. 1 and 5, electronic component 1012 illustrated in FIG. 10, or electronic component 12 illustrated in FIG. 13. Stated a different way, after step 604, major surface 129 of electronic component 12 is a non-parallel orientation with respect to major surface 110 of substrate 11 as illustrated in FIG. 5.

[0044] In an optional step 605, a package body can be provided to cover or encapsulate at least portions of the substrate and the electronic components. In some embodiments, package body 36 can be used and can be polymer based composite material, such as epoxy resin with filler, epoxy acrylate with filler, or polymer with proper filler. The package body may be formed using paste printing, compressive molding, transfer molding, over-molding, liquid encapsulant molding, vacuum lamination, other suitable applicator, or other processes as known to those of skill in the art. In some embodiments, an underfill material, such as underfill material 34 illustrated in FIG. 1, is placed between the electronic components and the substrate before the package body is provided.

[0045] Turning now to FIGS. 7-13 alternative embodiments will now be described. In FIGS. 7-9, 11, and 12, the electronic components are illustrated before the reflow process. Stated a different way, the electronic components have not yet be raised to an upright position. It is understood that after a reflow process, the electronic components in FIGS. 7-9, 11 and 12 are in a raised configuration. In FIGS. 10 and 13, the electronic components are illustrated in a raised configuration.

[0046] FIG. 7 illustrates a partial cross-sectional view of an electronic device 70 in accordance with an embodiment of the present description, which has an electronic component 712 attached at an edge 726 to conductive pattern 21 on substrate 11. Electronic device 70 is similar to electronic device 30, and only the main differences between the devices will be described hereinafter. In the present embodiment, substrate 11 is further provided with a structure 72, such as a stand-off 72, pad 72, or bump 72, which is configured to provide temporary support to electronic component 712 adjacent to major surface 731 before electronic component 712 is raised to an elevated position above major surface 110 of substrate 11. Structure 72 can comprise a material that does not adhere to electronic component 712 during the reflow process. In some embodiments, structure 72 comprises a polymer material, a ceramic material, or other materials known to those skilled in the art. In addition, electronic component 712 is provided with a conductive layer 728 on major surface 729 that is laterally spaced apart from conductive bump 32. More particularly, electronic component 712 is not in electrical communication with at least one conductive bump 32. Similar to electronic device 30, edge 726 of electronic component 712 overlaps only a portion of conductive pattern 21. In accordance with the present embodiment, edge 727 of electronic component 712, which is opposite to edge 726, is provided absent any conductive bumps 32. Stated a different way, conductive bumps 32 are disposed only along or next to edge 726 of electronic component 712.

[0053] In view of all of the above, it is evident that a novel method and related structures have been disclosed that provide an electronic component in an on-edge or an upright configuration. In some examples, an edge of an electronic component is placed adjacent a conductive pattern on a substrate. A conductive material is placed adjacent the edge and the conductive pattern. The conductive material is exposed to elevated temperature configured to reflow the conductive material. During the reflow process, a surface tension effect acts to raise or rotate the electronic component upward into an upright or on-edge orientation. In some examples, the conductive material includes a solder and conductive bumps, which can be substantially equally distributed along the edge of the electronic component. In some examples, the electronic component can be an antenna structure, such as a semiconductor antenna structure. In other examples, the electronic component can be a sensor device, such as an image sensor device. In some examples, the electronic component is a bare semiconductor die or chip (i.e., unpackaged). In some embodiments, the electronic component includes a conductive electrically connected to one or more of the conductive bumps disposed along the edge. In some examples, the conductive pattern can be on both sides of the electronic component. Multiple electronic components can be disposed on a substrate in both an on-edge configuration and in a conventionally attach configuration to provide an electronic device structure having 3-axis directional capability. The method and related structures described provide electronic device structure with enhanced design flexibility and performance. In addition, the method and relates structures that can support upcoming electronic component demands, such as 5G applications.
