Description of the Related Art Conventionally, there has been a solid-state imaging device in which a solid-state imaging device wired on a lead frame is integrally sealed with a transparent resin by a transfer molding method or the like from the viewpoint of low material cost and easy manufacturing. Among these solid-state imaging devices, there is one having a structure in which an on-chip lens 5 is provided on the upper surface of a solid-state imaging device 3 as shown in the schematic diagram of FIG. The on-chip lens 5 is formed by arranging minute convex lenses in units of one pixel. This is, as shown in the schematic diagram of FIG. 8, the refractive index n 0 of air and the refractive index n of the on-chip lens 5.
By utilizing the fact that 1 is n 0 <n 1 , the light is focused as shown by the arrow in the figure to increase the light receiving sensitivity.

However, if the upper part of the on-chip lens 5 is completely covered with the transparent resin 8 as shown in FIG. 9, the following problems occur. That is, the transparent refractive index n 2 of the resin 8 is greater than the refractive index n 0 of the air, so close to the refractive index n 1 of the on-chip lens, the refractive index n 1 and the refractive index n 2 of the transparent resin of the on-chip lens
Is n 1 ≒ n 2 . Therefore, as shown by an arrow in the figure, it is difficult for the light to be focused, so that the light receiving sensitivity is reduced as compared with the case where the air is above the on-chip lens 5 shown in FIG. Therefore, an object of the present invention is to provide a solid-state imaging device in which the focusing effect of an on-chip lens is not impaired even when the structure is integrally sealed with a transparent resin.

Next, the manufacturing process of the present invention will be described with reference to FIGS. 3A, 3B, 3C and 3D. In the step of FIG. 3A, first, the on-chip lens 5 is provided on the upper surface of the solid-state imaging device 3. Then, the solid-state imaging device 3 is mounted on the lead frame 2 and wired with the bonding wires 4. Note that the on-chip lens 5 may be provided after the solid-state imaging device 3 is mounted on the lead frame 2.

In the step of FIG. 3B, a thermosetting resin, for example, is applied as the support frame 6 projecting higher than the on-chip lens 5 in a state surrounding the solid-state image sensor 3. To apply the support frame 6, for example, a jig 20 for a lead frame as shown in FIG. 4 is used. At the center of the upper surface of the lead frame jig 20, a fluororesin 21 having low adhesion to the support frame 6 is provided. Then, the lead frame hole 23 is aligned with the positioning pin 22 to mount the solid-state imaging device,
Then, the lead frame 2 on which wiring has been completed is attached. If the support frame 6 is applied using the fluororesin 21 as an underlay, the support frame 6 does not flow out of the lead frame 2 or the gap of the lead frame 2. Also,
The support frame 6 cured as described later has a weak adhesiveness to the fluororesin 21 and can be easily separated.

Next, in the step of FIG. 3C, a transparent glass plate 7 is mounted on the upper surface of the support frame 6. To mount the transparent glass plate 7, for example, a holder 30 as shown in FIG. 5 is used. The holder 30 has a frame shape, and has a structure in which the transparent glass plate 7 is sandwiched between the inside of the frame and a fixed plate 31 with a notch. The transparent glass plate 7 is fixed by tightening a fixing screw 32 for pressing the fixing plate 31 from outside the frame. At this time, the transparent glass plate 7 is fixed so as to protrude from the bottom surface of the holder 30. This transparent glass plate 7
Is attached from above the lead frame 2 already attached to the lead frame jig 20. This mounting is performed by aligning the holder holes 33 with the positioning pins 22 in the same manner as the mounting of the lead frame 2. Thereby, the transparent glass plate 7 can be accurately held at a position where a gap can be formed between the transparent glass plate 7 and the on-chip lens 5. Then, in this state, the support frame 6 is cured by heat or the like, and the transparent glass plate 7 is mounted. Thereafter, the fixing screw 32 is loosened, the holder 30 is removed, and the lead frame 2 is removed from the lead frame jig 20. At this time, since the adhesion between the support frame 6 and the fluororesin 21 is weak, the lead frame 2 can be easily removed.

[0010] Then, in the step of FIG. 3 d, the supporting frame 6 on the lead frame 2 formed up to the previous step and the transparent glass plate 7 mounted on the upper surface thereof and forming a gap with the on-chip lens 5 are formed. Is entirely sealed with a transparent resin 8 by a transfer molding method or the like. Through the above steps, the solid-state imaging device 1 having the structure integrally sealed with the transparent resin 8 and having the space 9 between the on-chip lens 5 and the transparent glass plate 7 is manufactured.

Next, another embodiment of the present invention is shown in FIG.
The solid-state imaging device 1 is characterized by using a support frame 6 made of ceramic or the like in advance. Thereby, it becomes possible to attach the transparent glass plate 7 to the support frame 6 in advance. For example, as shown in FIG. 7A, after applying the adhesive 11 to the transparent glass plate 7 and attaching the support frame 6, as shown in FIG. 7B, the state where the transparent glass plate 7 is up and the support frame 6 is down. To The support frame 6 on which the transparent glass plate 7 is mounted is attached with the adhesive 11 so as to surround the entire solid-state imaging device 3 and the bonding wires 4 on the lead frame 2. At this time, adhesive 1
1 is also applied to a gap between the lead frames 2 and prevents the transparent resin 8 from entering the space 9 when integrally sealed with a transparent resin 8 described later. Since the upper surface of the support frame 6 is located at a position protruding from the on-chip lens 5,
A gap is formed between the transparent glass plate 7 mounted here and the on-chip lens 5. In this state, if the whole is integrally sealed with the transparent resin 8, the solid-state imaging device 1 in which the space 9 is provided between the on-chip lens 5 and the transparent glass plate 7 is obtained.

As described above, it is possible to form the solid-state imaging device 1 having the structure integrally sealed with the transparent resin 8 and having the space 9 between the on-chip lens 5 and the transparent glass plate 7. . Further, each of the support frames 6 in the present invention is formed so as to embed or surround the bonding wire 4 in the support frame. Therefore, since the bonding wire 4 is protected from the pressure applied during the molding of the transparent resin, deformation and disconnection are prevented. In addition, if the support frame 6 and the adhesive 11 are made of an opaque color, it is possible to block stray light that adversely affects an image.

As described above, according to the present invention, the structure is integrally sealed with a transparent resin, and a space can be provided between the on-chip lens on the upper surface of the solid-state imaging device and the transparent glass plate. . Accordingly, since the light focusing effect is greater than that of the structure in which the on-chip lens is covered with the transparent resin, the light receiving sensitivity can be increased. Further, since the structure is integrally sealed with a transparent resin by a transfer molding method or the like, the material cost is low, and the production is easy, so that the method is suitable for mass production. Furthermore, the pressure during transparent resin molding
Since the bonding wire does not receive force,
Without causing deformation or breakage of the bonding wire
We will be able to provide highly reliable products.
