An integrated imaging device using a packaging method that satisfies these conditions has conventionally been developed as shown in FIG. 111 or FIG. 2. In Mill, a substrate molded from 1Fi ceramic or the like, 2 is a solid-state image sensor, 3 is a conductive lead that electrically couples the element to an external circuit, and 4 is for transmitting original information to the light-receiving surface of the solid-state image sensor 2. A glass plate is generally used as a transparent flat plate. base [1 and transparent flat 1
In the hollow ii1 minute surrounded by the solid-state imaging device 2, the solid-state imaging device 2, the electrode 5 on the solid-state imaging device 2, and the bonding wire 6 connecting the solid-state imaging device 2 and the conductive lead 3 are protected against oxidation, moisture, etc. In order to prevent corrosion due to oxidation, it is generally filled with an inert gas such as an electric gas.

On the other hand, since the solid-state imaging device 2 is generally destroyed when heated to a high temperature of 200 to 250° C. or higher, it is not possible to seal the substrate, the transparent flat plate, and the low melting point glass together. For this purpose, the metal ring 11 is individually bonded to the substrate 1 and the transparent glass plate 114 with low-melting glass 8, and then the solid glass plate 2114 is attached to the substrate 111 in advance to connect the lead island and the solid-state image sensor 2. Connect between them with bonding wire 6*
The soft filler metal 89 metal ring 1 is heated locally to create an airtight seal.

However, in such a device, there are problems such as the structure of the sealing part is complicated, the number of sealing workers is large, the workability is poor, and the cost of the dangerous metal ring and gold thread brazing material is high. One drawback is that the packaging cost is extremely high.

In this case, the base III, the transparent flat plate 114, and the T-layer adhesive 10 are used for sealing. The hollow part is filled with inert gas as in the case of alR1 diagram. This solid-state imaging sm
#i It has a length of 79i, with a simple structure, easy sealing, and an extremely cheap pancasing cost. However, it has disadvantages in that water molecules and various gases enter from the outside into the inside through the organic adhesive 10, resulting in poor corrosion resistance and poor service life and reliability. When moisture enters the lens and reaches the dew point, a fatal problem can easily occur where dew condenses on the transparent F13 surface and prevents accurate transmission of information from the outside to the solid-state imaging atoms. . If an organic substance with a very small transparency such as polyvinylidene chloride resin is used as a substitute for the W-edge adhesive, the air resistance can be significantly improved, but it cannot be used in dormitories because of its poor adhesion to substrates and glass. There is 111 between them.
