- The present invention relates to a semiconductor device using a flexible circuit substrate, and more particularly to a semiconductor device composing a three-dimensional mounting module that is required to be inexpensive, smaller in size, and lighter in weight.
- Flexible circuit substrates have the advantage of being soft and deformable unlike rigid circuit substrates. Accordingly, they are advantageous in high-density mounting of ICs and size-reduction of modules. In other words, flexible circuit substrates are used for TCP (tape carrier packages), COF (Chip On Flexible or Film) and the like, and particularly they are indispensable for reducing the size of a variety of media apparatuses.
- Also, the system LSI technology is important in the realization of smaller, thinner and lighter media apparatuses. System LSIs are steadily advancing the technology towards the implementation of one-chip while incorporating LSIs of peripheral circuits. However, the development of a system LSI requires a long development time and results in an increased cost of the chip because of mixing of processes of different types. For this reason, requirements to be met by media apparatuses such as the short delivery time and low cost cannot be currently met.
- For the reasons described above, there are stronger demands in a system function mounting mainly composed of a three-dimensional mounting, and integration of a system LSI and the mounting technology is becoming more important. Frequency (high speed) and delivery (short-term delivery) determine the degree of growth in the media apparatus industry. Accordingly, the connection length and wiring length of an LSI to be built in must be shortened as much as possible by utilizing the mounting and packaging technologies. For this reason, three-dimensional mounting modules have been subject to various contrivances and have come into the stage of practical use.
- For example, conventionally, a three-dimensional mounting module has the following structure that has been placed in practice or in the stage of being placed in practice First, (A): TCPs (Tape Carrier Packages) are stacked in layers, and connection between the stacked chip layers is achieved by outer leads of the TCPs. (B): A frame body for wiring is disposed between layers of TCPs, and connection between the layers of the TCPs is achieved by the frame body. (C): Chips are stacked in layers, and the stacked chip layers are connected by conduction material. Also, other techniques are available.
- According to the conventional technology, stacked chip layers need to be electrically connected through certain interposers. The interposers may have a connection structure in which they are externally connected in a manner described above in (A) or (C), or a connection structure in which they are internally connected in a manner described above in (B). In any of the cases, a structure as a three-dimensional mounting module needs to be established first, then the electrical operation thereof as a module product is confirmed, and measurement and examination thereof can be conducted.
- If a three-dimensional mounting module is determined to be defective as a result of the measurement and examination, repair work (or re-work) to correct the defect is conducted. In other words, in a three-dimensional mounting module in the stage of assembling into a three-dimensional structure, it is important to provide a connection structure, which takes into consideration processes of how common electrodes and non-common electrodes are treated and how repair works (re-works) are conducted. In this respect, the conventional technology has problems of longer processing time and higher costs.
- The present invention has been made in view of the problems described above, and it is an object of the present invention to provide a semiconductor device having a three-dimensional mounting module structure using a flexible circuit substrate that is excellent in the workability in repair (re-work) works and handling readiness in the stage of assembling it into a three-dimensional structure.
- A semiconductor device in accordance with the present invention is characterized in comprising: a flexible circuit substrate having a base region and one or more mounting region continuously provided at a peripheral edge of the base region, wherein the mounting regions are folded over the base region; electronic components mounted corresponding to the mounting regions; a stacked layer support body including a thick first region and a foldable thin second region that is formed with the first region in one piece, each of the regions having a specified outer frame provided in a manner to protect each of the electronic components; a bonding member for integrating the stacked layer support body and the flexible circuit substrate in one piece, protruded sections provided at specified locations of the thick first region of the stacked layered support body, and aperture sections provided at specified locations in a rear surface side of the flexible circuit substrate to be coupled with the protruded sections, wherein, when the mounting regions of the flexible circuit substrate are folded together with the stacked layered support body over the base region, the protruded sections and the aperture sections are coupled and fixed together at an area where the thick first regions are superposed on top of the other through the flexible circuit substrate.
- In accordance with the semiconductor device of the present invention, at the time when the electronic components are mounted on the flexible circuit substrate, an operation as a module product can be conducted. Accordingly, measurement and examination can be conducted before they are assembled into a three-dimensional mounting module.
- Furthermore, the stacked layer support body for assembling a three-dimensional mounting module is formed in one piece and mounted on the flexible circuit substrate in one lot. Then, the mounting regions are folded and affixed together with the stacked layer support body on top of the other. As a result, a three-dimensional mounting module is realized in a fewer number of steps. In this instance, the protruded section and the aperture section that are pre-installed are coupled together, whereby positioning of the layers to be stacked is facilitated, and the assembly accuracy is improved.

- FIG. 1 shows a prospective view of a structure of a semiconductor device in accordance with a first embodiment of the present invention. FIG. 2 shows a perspective view of a characteristic assembly configuration with the structure shown in FIG. 1. As shown in FIG. 1, a
flexible circuit substrate 11 has a generallysquare base region 110 indicated by broken lines,mounting regions base region 110, and predetermined conduction patterns (not shown) formed below a protection film. Also, anexternal terminal section 115 is provided at the periphery of thebase region 110 in a region where the mounting regions are not provided. Theexternal terminal section 115 in this example is a connector terminal. - In the
flexible circuit substrate 11,electronic components mounting regions electronic components - The face-down mounting of the
electronic components flexible circuit substrate 11. Also, connection by an ACF (anisotropic conduction film) can be considered. More specifically, an ACF (anisotropic conduction film) is placed between the bump electrodes of each of the electronic components and the predetermined conduction patterns on theflexible circuit substrate 11 and they are heat-bonded together. As a result, conduction particles in the ACF achieve electrical connection between each of theelectronic components flexible circuit substrate 11. In addition, a variety of other methods may be employed. For, example, ACP (anisotropic conduction paste) bonding, NCP bonding that attains electrical connection by the shrinking force of an insulation resin, metal eutectic bonding of bumps between gold and gold, gold and tin or the like. Also, in some cases, a face-up mounting using the wire-bonding method can be applied. Furthermore, extremely thin IC packages can also be mounted. Therefore, electronic components are not limited to particular mounting configurations. - Also, some electronic components (peripheral elements) in small size relating to the
electronic components electronic components 124 may be capacitors, chip resistors or the like, and anelectronic component 125 may be a crystal or the like. - The
flexible circuit substrate 11 is formed from a soft material such as polyimide that can be freely bent. Theflexible circuit substrate 11 is formed such that themounting regions 111˜113 can be folded on top of the other in a predetermined order (f1˜f3) over thebase region 110. Therefore, distances d1˜d3 are set different from one another in consideration of the bending distances required for bending themounting regions 111˜113. - An integrated
spacer 13 is mounted on theflexible circuit substrate 11. The integratedspacer 13 is superposed over and affixed to the flexible circuit substrate as indicated by arrows with broken lines, such that they can support stacked layers of the electronic-components when themounting regions 111˜113 are folded on top of the other. The integratedspacer 13 hasthick regions 131 and athin region 132. - The
thick regions 131 of the integratedspacer 13 are provided to protect the stacked layers of theelectronic components 121˜123, and the otherelectronic components thick regions 131 has a configuration that surrounds, for example, each of the correspondingelectronic components 121˜123, respectively. Also, with respect to an electronic component in small size (e.g., 125) mounted adjacent to an edge, the thick region can have a configuration that partially extends along the periphery thereof. In any case, thethick regions 131 may preferably have outer frame shapes that can be superposed over thebase region 110 since they are stacked over thebase region 110. - The
thin region 132 of theintegrated spacer 13 extends over thebase region 110, and is formed in one piece with thethick regions 131. Thethin region 132 forms a region that can be bent at least along the periphery of thebase region 110. Also, anopening section 133 may be provided such that mounting of theelectronic component 124 is not prevented. - The integrated
spacer 13 can be composed of, for example, a formed product of polyimide resin in consideration of heat resistance. Thethick regions 131 have a thickness to the extent that the electronic components (121˜123 and the like) to be mounted are not prevented from being stacked in layers. Also, thethin region 132 may preferably be as thin as possible because it includes a bending section, and may preferably have a thickness of about 0.1˜0.2 mm, for example. If handling of theintegrated spacer 13 is not difficult, thethin region 132 can be much thinner. - The integrated
spacer 13 is affixed on its rear surface (not shown) to theflexible circuit substrate 11 through a bonding member such as a two-faced tape, adhesive or the like, such that it forms an integrated structure with theflexible circuit substrate 11. - Fixing
bosses 134 are pre-installed at specified locations on thethick regions 131 of theintegrated spacer 13. Also, as shown in FIG. 2,aperture sections 14 to be coupled with the fixingbosses 134 are provided in rear surface of the mountingregions flexible circuit substrate 11 at locations corresponding to thethick region 131 of theintegrated spacer 13. - FIG. 2 shows the
aperture sections 14 provided on the rear surface side of the mountingregion 111, which are coupled with the fixingbosses 134 on the mountingregion 112, as indicated by arrows with broken lines. Although not shown, theaperture sections 14 to be coupled with the fixingbosses 134 on the mountingregion 113 are provided on the rear surface side of the mountingregion 112. - Each of the
aperture sections 14 requires a depth in which each of the fixingbosses 134 is inserted, and therefore it is formed in a manner that it passes through the flexible circuit substrate 11 (a through hole H shown in FIG. 1) and penetrates into a part of thethick region 131 from its rear surface side. Furthermore, bonding members such as adhesive, two-faced tapes or the like are provided on stacking layer fixing sides (hatched areas) of thethick regions 131. By these members, theelectronic components 121˜123 (including the other small-sized electronic components) are successively stacked in layers. In this instance, the fixingbosses 134 and theaperture sections 14 are coupled and affixed with one another in areas where thethick regions 131 of theintegrated spacer 13 are stacked on top of the other through theflexible circuit substrate 11. - FIG. 3 shows a cross-sectional view of an assembled configuration of the semiconductor device of FIG. 1. For ready understanding of the assembled state, the flexible circuit substrate folded at the front thereof is also shown by phantom lines. More specifically, in an embodiment shown here, the mounting
regions base region 110 from the respective directions, such that theelectronic components electronic components - The integrated
spacer 13 is affixed to theflexible circuit substrate 11 through, for example, a two-faced tape. Furthermore, adhesive regions (for example, two-faced tapes) 20 provided on thethick regions 131 contribute to affixing the stacked layers. As a result, theelectronic components electronic components thick regions 131. - A
thin region 132 of theintegrated spacer 13 supports bending regions of theflexible circuit substrate 11, and plays a role of protecting theflexible circuit substrate 11 particularly with respect to its bendingend regions - Furthermore, the fixing
bosses 134 and theaperture sections 14 engage with one another to thereby contribute to folding and positioning of the mounting regions of theflexible circuit substrate 11 with theintegrated spacer 13. A bonding member may be provided between the fixingbosses 134 and theaperture sections 14. - In accordance with the first embodiment of the present invention, at the time when the electronic components (121˜123 and others) are mounted on the
flexible circuit substrate 11, an operation as a module product can be conducted. Accordingly, measurement and examination can be conducted before they are assembled into a three-dimensional mounting module. - Moreover, the
integrated spacer 13 that can be assembled into a three-dimensional mounting module can be mounted on theflexible circuit substrate 11 in one lot. Then, the mountingregions 111˜113 together with theintegrated spacer 13 are folded and affixed on top of the other to realize a three-dimensional mounting module of the electronic components (121˜123 and others). - It is noted that, in the first embodiment, the fixing
bosses 134 are not provided on thethick regions 131 that are initially folded over thebase region 110. However, they may be provided. In such an instance, apertures to be coupled with the fixingbosses 134 are needed in thethin region 132 of theintegrated spacer 13 over thebase region 110. - By doing so, the accuracy in assembly positions is improved when the mounting regions are initially stacked. However, when a three-dimensional module having such a structure is mounted on a main substrate, it is important to make an arrangement so that the fixing
bosses 134 that are present on thebase region 110 do no prevent the mounting work. For example, as a countermeasure, thebosses 134 are made to be low such that they do not protrude from thebase region 110. Alternatively, recesses (recesses) may be provided in the main substrate at locations corresponding to thebosses 134 to avoid (or alleviate) collision with thebosses 134. - Moreover, in the embodiment described above,
apertures 14 are not provided on thethick regions 131 in the mountingregion 113 that is lastly folded over thebase region 110. However, they may be provided in a manner to pass through theflexible circuit substrate 11. In this case, they contribute to positioning when a heat sink or the like is provided on the three-dimensional module. - As a result, the assembly characteristic (readiness and accuracy in assembly) of a three-dimensional mounting module is substantially improved, and the number of work steps can be reduced. This results in an excellent workability in repair work (or re-work). The assembly characteristic is improved and the number of parts is reduced compared to spacers of a separated type. This contributes to the reduction of costs. Also, due to the improved positioning accuracy attained by the engagement between the fixing
bosses 134 and theaperture sections 14, there is provided an advantage in that a product can be designed with much smaller clearances. As a result, a more compact three-dimensional mounting module can be attained. - In the three-dimensional mounting module in accordance with the present invention, the electronic components (121˜123 and others) are mounted on the
flexible circuit substrate 11, and folded over on top of the other together with theflexible circuit substrate 11 and theintegrated spacer 13. This configuration substantially loosens the restrictions on the size of ICs and placements of the pads, compared to a stacked package in which IC chips are stacked on top of the other. In a stacked package, there are a variety of restrictions on the size of ICs that are combined, IC terminal positions and the like. In contrast, a three-dimensional mounting module in accordance with the present invention has a greater degree of freedom in selection and combination of different types of ICs, and provides an electrically most optimized module in view of the fact that a plurality of peripheral elements can also be mounted. - FIGS.4(a) and (b) show a structure of a semiconductor device in accordance with a second embodiment of the present invention, respectively, wherein FIG. 4(a) shows a plan view before assembly, and FIG. 4(b) schematically shows a cross-sectional view of a characteristic general structure of a three-dimensional mounting module after assembly.
- For ready understanding of the assembled state, the flexible circuit substrate folded at the front thereof is also shown by phantom lines. Elements that are the same as those of the first embodiment are referred to by the same reference numbers and the description thereof is omitted.
- In the second embodiment of the present invention, a
flexible circuit substrate 41 is different from that of the first embodiment. As shown in the figure, anelectronic component 126 is also mounted on thebase region 110 of theflexible circuit substrate 41. Accordingly, theintegrated spacer 13 is also provided with athick region 131 on thebase region 110 corresponding to theelectronic component 126. - Also, in view of the fact that the
electronic components 121˜123 are successively stacked over theelectronic component 126 in layers, in theintegrated spacer 13, distances d11˜d13 between thethick region 131 on thebase region 110 and thethick regions 131 on the mountingregions 111˜113, respectively are made different from one another. - Furthermore, fixing
bosses 134 are provided at specified locations on thethick region 131 of theintegrated spacer 13 over the mountingregion 111. Also,aperture sections 14 to be coupled to the fixingbosses 134 are provided in thethick region 131 of theintegrated spacer 13 provided on thebase region 110. - With this structure, the
flexible circuit substrate 41 is folded over in a predetermined order together with the integrated spacer 13 (the thick regions 131). In other words, theelectronic components 121˜125 are stacked and fixed in layers in a similar manner as described in the first embodiment (see FIG. 4(b)). - FIGS.5(a) and (b) show a structure of a semiconductor device in accordance with a third embodiment of the present invention, wherein FIG. 5(a) shows a plan view before assembly, and FIG. 5(b) schematically shows a cross-sectional view of a characteristic general structure of a three-dimensional mounting module after assembly. For ready understanding of the assembled state, the flexible circuit substrate folded at the front thereof is also shown by phantom lines. Elements that are the same as those of the second embodiment are referred to by the same reference numbers and the description thereof is omitted.
- In the third embodiment of the present invention, a
flexible circuit substrate 51 is different from that of the first embodiment. As shown in the figure, external terminal sections (for example, ball electrodes) 52 indicated by broken lines are provided on the rear surface of thebase region 110 of theflexible circuit substrate 51. In other words, in this structure, the externalterminal section 115 described in the first embodiment (in FIG. 1), which is a connector terminal, is replaced with an array type electrode (52). - End sections of the conduction patterns, which are equivalent to external terminals (not shown), are connected to the external terminal sections (ball electrodes)52 through via patterns (not shown) in the main surface of the flexible circuit substrate 61 in which the mounting regions (111˜113) are provided.
- Also, an
electronic component 125 is a crystal, which is an SMD (Surface Mount Device) type instead of a cylinder type described above. An SMD type can be subject to a reflow when a three-dimensional module is mounted on a main substrate by solder and therefore is reliable. - The integrated
spacer 13 is provided withthick regions 131 in accordance with theelectronic components 121˜125. Accordingly, theflexible circuit substrate 51 is folded over on top of the other in a predetermined order together with the integrated spacer 13 (with the thick regions 131). Namely, the fixingbosses 134 and theaperture sections 14 are coupled together and theelectronic components 121˜125 are stacked and affixed in layers in a similar manner as described in the first embodiment (see FIG. 5(b)). - The
electronic components 121˜125 may be affixed in advance to the flexible circuit substrate 61 by an adhesive means such as a thermosetting type adhesive depending on the requirements. This would contribute toward preventing, for example, theelectronic components spacer 13. - In one possible structure, mounting regions may be provided along all of the four edges of the periphery of the
base region 110. In such a case, electronic components are stacked in layers in a predetermined order together with an integrated spacer including thick regions and a thin region and affixed together in the same manner as described in the first embodiment. - Both of the second and third embodiments described above are made in pursuit of a high-density mounting structure. In accordance with these embodiments, at the time when the electronic components are mounted on the
flexible circuit substrate - Moreover, the
integrated spacer 13 that can be assembled into a three-dimensional mounting module can be mounted on theflexible circuit substrate integrated spacer 13 and affixed on top of the other. In this instance, since the fixingbosses 134 and theaperture sections 14 that are pre-installed engage one another, the positioning work becomes substantially easy. - It is noted that the number and locations of the fixing
bosses 134 and theaperture sections 14 are not particularly limited, and they can be provided at any locations necessary for positioning or affixing. As described above in the first embodiment, fixing bosses for aligning the positions thereof with respect to thebase region 110 may be provided on thethick region 131 that is initially folded over thebase region 110, and aperture sections may be provided on the base region. However, as described above, it is important to provide a structure in which the fixingbosses 134 existing on thebase region 110 do not hinder the mounting work. - Furthermore, apertures that pass through the
flexible circuit substrate 11 may be provided on thethick regions 131 in the mounting region that is lastly folded over thebase region 110. As a result, they contribute to positioning when a heat sink or the like is provided on the three-dimensional module. - In accordance with the embodiments described above, due to the integrated spacer together with engagement of the fixing bosses and the aperture sections, the assembly characteristic (readiness and accuracy in assembly) is substantially improved, and a product can be designed with much smaller clearances. This provides a three-dimensional mounting module having an excellent workability in repair work (or re-work). The assembly characteristic is improved and the number of parts is reduced compared to spacers of a separated type This contributes to the reduction of costs. Furthermore, a greater degree of freedom in combining different types of ICs is available and a most electrically optimized module can be obtained in view of the fact that a plurality of peripheral elements can be mounted.
- As a result, there is provided a most electrically optimum semiconductor device with the high degree of freedom can be provided with a highly reliable three-dimensional mounting module using a flexible circuit substrate, in which the readiness and controllability are attained in assembling the high density three-dimensional mounting module, and an excellent workability in repair work (or re-work).
