Hereinafter, each embodiment will be described with reference to the accompanying drawings. Note that the attached drawings are for explaining the outline of the structure and do not represent the actual size.
As shown in FIG. 1A, a semiconductor package 1 used for a camera module includes a wiring board 10, an image sensor 20 mounted on the wiring board 10, and a frame shape fixed on the image sensor 20. The member 30 and the cap member 50 fixed to the frame-shaped member 30 are included.
The wiring substrate 10 includes a substrate body 11, a through electrode 12 that penetrates in the thickness direction of the substrate body 11, and wiring patterns 13 and 14. As the substrate body 11, for example, a glass epoxy substrate can be used. The substrate body 11 is formed with through holes 11X at required locations (two locations in FIG. 1A). The through hole 11X is formed so as to penetrate from the first main surface 11A to the second main surface 11B of the substrate body 11.
The through electrode 12 is provided in the through hole 11X. The through electrode 12 has one end connected to the wiring pattern 13 and the other end connected to the wiring pattern 14.
The wiring pattern 13 is formed on the first main surface 11A (the mounting surface on which the imaging element 20 is mounted) of the substrate body 11. In addition, the wiring pattern 14 is formed on the second main surface 11B (surface opposite to the mounting surface) of the substrate body 11. The wiring patterns 13 and 14 are electrically connected to each other through the through electrode 12. In addition, as a material of the penetration electrode 12 and the wiring patterns 13 and 14, metals, such as copper (Cu), can be used, for example.
The image sensor 20 is fixed on the first main surface 11A of the substrate body 11 with its light receiving surface (upper surface 20A) facing upward. As the image sensor 20, for example, a CMOS image sensor or a CCD image sensor can be used. The connection pad 21 of the image pickup device 20 is electrically connected to the wiring pattern 13 of the wiring substrate 10 through the wire 22.
A frame-shaped member 30 is bonded on the image sensor 20. Specifically, the frame-shaped member 30 is bonded onto the upper surface 20 </ b> A of the imaging element 20 with an adhesive 23. More specifically, the frame-shaped member 30 is bonded onto an area (for example, an optical black area) outside the effective pixel area A1 (see FIG. 1B) of the image sensor 20. In other words, the frame-shaped member 30 is adhered on the image sensor 20 so as to surround the effective pixel area A1 of the image sensor 20 (a region such as a light receiving unit that affects the imaging characteristics). The material of the frame-shaped member 30 is not particularly limited as long as it is insulating, can be processed into a desired shape, and has sufficient strength. Further, when the semiconductor package 1 is solder-mounted on the mother board, the frame-shaped member 30 is preferably a material having heat resistance of about 250 ° C. to 270 ° C. For example, as a material of the frame-shaped member 30, a resin such as polycarbonate (PC) or polyphenylene sulfide (PPS) can be used. As the adhesive 23, a thermosetting adhesive can be used. As the thermosetting adhesive, an epoxy adhesive, a urethane adhesive, or the like can be used.
The frame-shaped member 30 includes a frame-shaped (frame-shaped) frame base portion 31 whose bottom surface is bonded to the imaging element 20 via an adhesive 23, and a frame-shaped adhesive portion 32 wider than the frame base portion 31. And a standing portion 33 which is formed on the outer periphery of the bonding portion 32 and stands upward. The frame base portion 31, the bonding portion 32, and the standing portion 33 are integrally molded (formed).
For example, the frame base 31 has a height H1 of 300 μm and a width W1 of 500 μm. The bonding portion 32 is formed on the upper surface of the frame base portion 31. The bonding portion 32 is formed so that the inner peripheral surface thereof is outside the inner peripheral surface of the frame base portion 31. Accordingly, a step portion 30 </ b> D is formed on the inner peripheral surface of the frame-shaped member 30. That is, on the inner peripheral surface of the frame-shaped member 30, a bottom surface side member (here, the frame base portion 31) protrudes inward from the inner peripheral end of the upper surface 32A of the bonding portion 32 to form a step portion 30D. ing. Further, the adhesive portion 32 is formed so that the outer peripheral surface thereof protrudes outside the outer peripheral surface of the frame base portion 31. For example, the bonding portion 32 is set to have a height H2 of 200 μm and a width W2 of 600 μm.
A concave portion 32X is formed on the upper surface 32A (adhesion surface) of the adhesion portion 32. The recess 32X is formed from the upper surface 32A of the bonding portion 32 to the middle of the thickness. Further, as shown in FIG. 1B, the recess 32X is formed in an annular and belt-like shape in plan view. For example, the recess 32X has a width W3 set to, for example, 100 μm and a depth H3 (see FIG. 1A) set to 100 μm.
As shown in FIG. 1A, the standing portion 33 is formed so as to surround the cap member 50 bonded on the bonding portion 32. The standing portion 33 is set to have a height H4 of 400 μm and a width W4 of 100 μm, for example.
A cap member 50 is bonded to the upper surface 32 </ b> A of the bonding portion 32 of the frame-shaped member 30 with an adhesive 40. The adhesive 40 is applied to the upper surface 32A of the adhesive portion 32 and is filled in the concave portion 32X. Further, the adhesive 40 is also formed between the standing portion 33 and the cap member 50. As the adhesive 40, a thermosetting type and an ultraviolet (UV) curable type adhesive can be used. As the thermosetting and UV curable adhesives, epoxy adhesives, acrylic adhesives, and the like can be used.
The cap member 50 is a rectangular flat glass plate. The cap member 50 has a size of 8 mm × 6 mm, for example. When the cap member 50 is fixed onto the frame-shaped member 30, the space S1 formed by the imaging element 20, the frame-shaped member 30, and the cap member 50 is hermetically sealed, and the space S1 is isolated from the outside air. This prevents dust from adhering to the image sensor 20 (particularly on the effective pixel area A1) and prevents the incident from entering the image sensor 20 from being blocked by the dust. Is done. The cap member 50 also functions as an IR cut filter that removes light in an IR (infrared) region other than visible light from outside light.
A sealing resin 60 is formed on the imaging element 20 and the wiring board 10 arranged outside the frame-shaped member 30. The sealing resin 60 is formed in contact with the lower surface of the bonding portion 32 and the lower surface of the standing portion 33 of the frame-shaped member 30. More specifically, the sealing resin 60 is formed so as to fill a space between the lower surface of the bonding portion 32 and the wiring substrate 10 and the imaging element 20. Thereby, the frame-shaped member 30 is bonded onto the imaging element 20 by the adhesive 23 and supported by the sealing resin 60. Further, the wiring pattern 13, the connection pad 21, the wire 22, and the like are sealed by the sealing resin 60. As a material of the sealing resin 60, for example, an insulating resin such as an epoxy resin or a polyimide resin can be used. Specifically, as the sealing resin 60, a potting resin formed by a potting method can be used.
Next, the operation of the semiconductor package 1 adopting such a structure will be described.
In the semiconductor package 1, the frame-like member 30 is provided on the image sensor 20. This eliminates the need for a space for disposing the frame-shaped member 30 on the wiring board 10, thereby reducing the size of the wiring board 10 and reducing the size of the semiconductor package 1. Further, the space between the bonding portion 32 and the wiring board 10 and the image sensor 20 is filled, and the frame-shaped member 30 is supported by the sealing resin 60 formed so as to be in contact with the lower surface of the bonding portion 32. . Thereby, the frame-shaped member 30 can be firmly supported together with the bonding between the frame base portion 31 and the imaging element 20 by the adhesive 23.
Here, as a method of strengthening the support of the frame-shaped member 30, for example, the cross section of the wiring board 10 is formed in a U-shape, that is, protrusions that protrude upward are provided at both ends of the wiring board 10, A method of supporting the frame-shaped member 30 (adhesive portion 32) with the protruding portion is also conceivable. However, in this case, since the protruding portion needs to be formed in a region outside the wiring pattern 13, there is a problem that the wiring substrate 10 is increased in size and the semiconductor package is increased in size. On the other hand, in the semiconductor package 1 of the present embodiment, the sealing resin 60 can be formed in the space between the lower surface of the bonding portion 32 and the wiring substrate 10 and the imaging element 20. Therefore, it is not necessary to unnecessarily increase the outer shape of the frame-shaped member 30. Furthermore, in order to strengthen the support of the frame-shaped member 30, it is not necessary to provide a member that is unnecessarily larger than the outer shape of the frame-shaped member 30. Thereby, the enlargement of the semiconductor package 1 can be suppressed suitably.
In addition, the imaging element 20 and the cap member 50 are separated from each other by the frame-shaped member 30 that is a molded product. For this reason, the distance (air gap) from the upper surface 20A of the image sensor 20 to the lower surface of the cap member 50 can be adjusted to a desired distance by appropriately adjusting the height of the frame-shaped member 30. As a result, a large air gap can be secured, so that management specifications such as scratches, dirt and attached foreign matter on the glass plate as the cap member 50 can be relaxed, leading to an improvement in yield.
In the frame-shaped member 30, an adhesive portion 32 having a width wider than that of the frame base portion 31 is provided on the upper surface of the frame base portion 31. Thereby, since the contact area of the adhesion part 32 (adhesive 40 apply | coated to 32 A of upper surfaces) and the cap member 50 can be enlarged, the adhesion part 32 and the cap member 50 can be adhere | attached firmly.
Furthermore, an annular recess 32X is formed on the upper surface 32A of the bonding portion 32. Then, the adhesive 40 is filled in the concave portion 32 </ b> X, and the adhesive 40 is applied to the upper surface 32 </ b> A of the adhesive portion 32. Thus, the adhesive agent 40 can be formed thick by being filled with the adhesive agent 40 in the recessed part 32X. That is, the adhesive 40 having a lower elastic modulus than the frame-shaped member 30 and the cap member 50 can be formed thick. Thus, even when heat treatment is performed, for example, when the semiconductor package 1 is solder-mounted on a mother board or the like, the thermal stress between the frame-shaped member 30 and the cap member 50 is relieved by the thick adhesive 40. Can do. Specifically, since the difference between the thermal expansion coefficient of the frame-shaped member 30 and the thermal expansion coefficient of the cap member 50 is absorbed by the elastic deformation of the adhesive 40, the thermal stress generated due to the difference between the thermal expansion coefficients of each other is absorbed. Can be relaxed. Therefore, occurrence of problems such as warping of the cap member 50 can be suppressed.
Next, a method for manufacturing the semiconductor package 1 will be described.
First, a wiring board 10 as shown in FIG. The wiring board 10 is formed with a through hole 11X, a through electrode 12, and wiring patterns 13 and 14 using a known technique.
Next, as shown in FIG. 2B, the imaging element 20 is mounted on the first main surface 11A of the wiring board 10 with the light receiving surface facing upward (die bonding). Subsequently, the connection pads 21 of the image sensor 20 and the wiring pattern 13 of the wiring substrate 10 are electrically connected by wires 22 (wire bonding).
Here, the frame-shaped member 30 shown in FIG. 1, that is, the frame-shaped member 30 in which the concave portion 32 </ b> X is formed on the upper surface 32 </ b> A of the adhesive portion 32 wider than the frame base portion 31 is prepared. The frame-shaped member 30 can be obtained by batch molding, for example, by pouring a resin such as polycarbonate or polyphenylene sulfide into a mold, and quenching and solidifying the resin. The frame member 30 may be formed by printing or the like, and the manufacturing method is not particularly limited as long as the frame member 30 can be formed in an arbitrary shape.
Next, as illustrated in FIG. 2C, a thermosetting adhesive 23 is applied to the upper surface 20 </ b> A of the image sensor 20 in a frame shape along the outer peripheral surface (outer shape) of the image sensor 20. The adhesive 23 is applied so as not to spread over the effective pixel area A1 (see FIG. 1B) of the image sensor 20. Then, the frame-shaped member 30 is disposed on the adhesive 23. Specifically, the frame-shaped member 30 is arranged on the imaging element 20 so that the bottom surface of the frame base portion 31 of the frame-shaped member 30 is in contact with the adhesive 23.
Next, the adhesive 23 is cured by heat treatment at a predetermined temperature (for example, about 85 ° C.). Thereby, the frame-shaped member 30 is bonded to the upper surface 20 </ b> A of the imaging element 20.
Next, as shown in FIG. 2D, the concave portion 32 </ b> X of the bonding portion 32 of the frame-shaped member 30 is filled with the UV curable and thermosetting adhesive 40 and the adhesive 40 is applied to the upper surface 32 </ b> A of the bonding portion 32. Apply.
2E, a cap member 50 having a size slightly smaller than the outer shape of the bonding portion 32 of the frame-shaped member 30 is prepared, and the cap member 50 is disposed on the upper surface 32A of the bonding portion 32. . Thereby, the space S1 surrounded by the image sensor 20, the frame-shaped member 30, and the cap member 50 is sealed, and the effective pixel area A1 of the image sensor 20 in the space S1 is isolated from the outside air. When the cap member 50 is disposed on the upper surface 32 </ b> A of the bonding portion 32, the adhesive 40 on the bonding portion 32 spreads in the width direction of the bonding portion 32. At this time, since the standing portion 33 is formed at the outer peripheral end of the bonding portion 32, the adhesive 40 spreading in the width direction spreads in the height direction along the inner wall of the standing portion 33. Thereby, the adhesive 40 is also formed between the standing portion 33 and the cap member 50. On the other hand, since the step portion 30D is formed on the inner peripheral side of the adhesive portion 32 by the frame base portion 31 protruding inward from the inner peripheral surface of the adhesive portion 32, the adhesive 40 spreads in the width direction. Falls on the image sensor 20.
Next, after the adhesive 40 is semi-cured by UV irradiation, the adhesive 40 is completely cured by heat treatment at a predetermined temperature (for example, about 85 ° C.). Thereby, the occurrence of a problem such as the cap member 50 being lifted due to air expansion in the space S <b> 1 is suppressed, and the cap member 50 is bonded to the upper surface 32 </ b> A of the bonding portion 32. At this time, since the adhesive 40 is formed not only on the upper surface 32A of the bonding portion 32 but also between the standing portion 33 and the cap member 50, the cap member 50 is firmly bonded to the frame-shaped member 30. Can do.
Subsequently, as shown in FIG. 3A, a dam 61 is formed on the first main surface 11 </ b> A of the substrate main body 11 in a region outside the wiring pattern 13. Here, as shown in FIG. 4A, when a multi-chip substrate 10A on which a large number of semiconductor packages 1 are formed is used, a dam 61 is formed in a frame shape along the outer shape of the substrate 10A. . As the material of the dam 61, a material having a high viscosity is preferable. For example, an epoxy resin can be used. The dam 61 is formed by a method of attaching a frame-like frame, a method of manufacturing a glass epoxy substrate (a method such as a photolithography method or a printing method), or the like.
Next, as shown in FIG. 4B, the sealing resin 60 is injected into the region surrounded by the dam 61 by potting, and the sealing resin 60 is cured by heating. As shown in FIG. 3B, the sealing resin 60 fills the space between the lower surface of the adhesive portion 32 and the lower surface of the standing portion 33 of the frame-shaped member 30 and the imaging element 20 and the wiring substrate 10. Injected into. 3B, the frame-shaped member 30 is supported by the sealing resin 60, and the wiring pattern 13, the connection pad 21, and the wire 22 are sealed by the sealing resin 60. In this step, the dam 61 functions as a member that blocks the sealing resin 60.
Subsequently, as shown in FIG. 3C, the semiconductor device 1 is manufactured by cutting the structure shown in FIG. 3B along the dicing position B into pieces.
(1) In the semiconductor package 1, the frame-like member 30 is provided on the image sensor 20. This eliminates the need for a space for disposing the frame-shaped member 30 on the wiring board 10, thereby reducing the size of the wiring board 10 and reducing the size of the semiconductor package 1. Further, the space between the bonding portion 32 and the wiring board 10 and the image sensor 20 is filled, and the frame-shaped member 30 is supported by the sealing resin 60 formed so as to be in contact with the lower surface of the bonding portion 32. . Thereby, the frame-shaped member 30 can be firmly supported together with the bonding between the frame base portion 31 and the imaging element 20 by the adhesive 23.
(2) The concave portion 32X is formed on the upper surface 32A of the bonding portion 32. Then, the adhesive 40 is filled in the concave portion 32 </ b> X, and the adhesive 40 is applied to the upper surface 32 </ b> A of the adhesive portion 32. Thus, the adhesive 40 having a lower elastic modulus than that of the frame-shaped member 30 and the cap member 50 can be formed thicker by filling the concave portion 32 </ b> X with the adhesive 40. As a result, when the semiconductor package 1 is subjected to heat treatment, the difference between the thermal expansion coefficient of the frame-shaped member 30 and the thermal expansion coefficient of the cap member 50 is absorbed by the elastic deformation of the adhesive 40, so The thermal stress generated by the difference can be relaxed. Therefore, occurrence of problems such as warping of the cap member 50 can be suppressed.
(3) The recess 32X is formed in an annular shape. Thereby, since the concave portions 32X are uniformly formed on the upper surface 32A of the bonding portion 32, the thermal stress can be relieved on the entire upper surface 32A of the bonding portion 32. Therefore, occurrence of problems such as warping of the cap member 50 can be effectively suppressed.
In addition, the said embodiment can also be implemented in the following aspects which changed this suitably.
In the above embodiment, the cap member 50 is bonded onto the frame-shaped member 30 after the frame-shaped member 30 is bonded onto the imaging element 20. For example, after the cap member 50 is bonded onto the frame-shaped member 30, the frame-shaped member 30 may be bonded onto the imaging element 20. A method for manufacturing the semiconductor package 1 in this case will be described below.
As shown in FIG. 5A, before the frame-shaped member 30 is bonded to the imaging element 20, the concave portion 32X of the bonding portion 32 of the frame-shaped member 30 is filled with the adhesive 40A and the upper surface 32A of the bonding portion 32 is used. The adhesive 40A is applied to the surface. As the adhesive 40A, a thermosetting adhesive can be used. As the thermosetting adhesive, an epoxy adhesive, a urethane adhesive, or the like can be used.
Next, as shown in FIG. 5B, the cap member 50 having a size slightly smaller than the outer shape of the bonding portion 32 of the frame-shaped member 30 is disposed on the upper surface 32 </ b> A of the bonding portion 32. Subsequently, the adhesive 40A is cured by heat treatment at a predetermined temperature (for example, about 85 ° C.). Thereby, the cap member 50 is bonded to the upper surface of the frame-shaped member 30.
On the other hand, as shown in FIG. 5C, an adhesive 23 </ b> A is applied to the upper surface 20 </ b> A of the image sensor 20 mounted on the wiring substrate 10 in a frame shape along the outer peripheral surface of the image sensor 20. As the adhesive 23A, a thermosetting adhesive and a UV curable adhesive can be used. As the thermosetting and UV curable adhesives, epoxy adhesives, acrylic adhesives, and the like can be used.
Next, as illustrated in FIG. 5D, the frame-shaped member 30 to which the cap member 50 is bonded is disposed on the imaging element 20. Specifically, the frame-shaped member 30 is disposed on the imaging element 20 so that the bottom surface of the frame base portion 31 of the frame-shaped member 30 is in contact with the adhesive 23A. Subsequently, after the adhesive 23A is semi-cured by UV irradiation, the adhesive 23A is completely cured by heat treatment at a predetermined temperature (for example, about 85 ° C.). As a result, the frame-shaped member 30 to which the cap member 50 is bonded is bonded to the upper surface 20A of the image sensor 20.
In addition, since the subsequent manufacturing process can be implemented similarly to the process shown to Fig.3 (a)-FIG.3 (c), description is abbreviate | omitted here.
As shown in FIG. 6, a structure in which the standing portion 33 is omitted from the frame-like member 30 can be adopted.
-As the sealing resin 60 of the said embodiment, the potting resin formed by the potting method was used. Not limited to this, as shown in FIG. 7, for example, as the sealing resin 60A, a mold resin formed by a transfer molding method, a compression molding method, an injection molding method, or the like may be used. In the example of FIG. 7, the sealing resin 60 </ b> A is formed so that the upper surface of the sealing resin 60 </ b> A and the upper surface of the standing portion 33 of the frame-shaped member 30 are flush with each other.
As shown in FIG. 8, the inner diameter of the inner peripheral surface 30 </ b> A of the frame-shaped member 30 (the frame base portion 31 and the bonding portion 32) decreases from the bottom surface of the frame base portion 31 toward the upper surface 32 </ b> A of the bonding portion 32. You may make it form in a taper shape. According to this, since the bottom area of the frame base portion 31 disposed on the upper surface 20A of the image pickup device 20 is reduced, the application region of the adhesive 23 that bonds the image pickup device 20 and the frame-shaped member 30 can be reduced. it can. Therefore, it is possible to suitably suppress the adhesive 23 from spreading over the effective pixel region A1 of the image sensor 20.
In the above embodiment, the concave portion 32X of the bonding portion 32 is formed in an annular shape, but is not limited to this shape. For example, as shown in FIG. 9, linear concave portions 32 </ b> X may be formed on the four sides of the upper surface 32 </ b> A of the bonding portion 32 of the frame-shaped member 30. Further, the concave portions 32X may be formed so as to be scattered on the upper surface 32A of the bonding portion 32.
In the above embodiment, the frame base member 31, the bonding portion 32, and the standing portion 33 are integrally molded to form the frame-shaped member 30. For example, the frame base portion 31 and the bonding portion 32 are erected. The frame member 30 may be formed by bonding the portion 33 with an adhesive or the like.
In the above embodiment, the image sensor 20 is mounted on the wiring board 10, but an electronic component other than the image sensor 20 may be mounted on the wiring board 10.
