う問題が生じ易、い。In general, semiconductor drop-down circuit devices such as photosensors and CODs have a light-receiving element and other elements integrally formed on the same semiconductor substrate, and receive optical signals from the outside using the light-receiving pair and convert them into electrical signals. K is designed to convert the signal and perform various signal processing using other elements. However, in such a device, when an element other than the light-receiving element (hereinafter referred to as other element) is irradiated with light, a charge is generated by the light energy in the PN junction of the element or deeper in the semiconductor substrate. (electrons and holes) are generated, which tends to cause the problem of inducing device malfunction.

構成では集積度の向上には限度がある。However, since the light-receiving element and other elements are integrally formed through the same semiconductor substrate, the light-receiving element to which the light is irradiated and the semiconductor substrate at a deeper position may be affected. It is difficult to reliably prevent the malfunctions mentioned above.
In addition, in a configuration in which the light receiving element and other elements are arranged on the same semiconductor substrate in a plane (-2 dimension), the degree of integration decreases. There are limits to how much improvement can be made.

In addition, the front serpentine light film 4 is covered with a light-transmitting Pudge Page film 10 formed by forming a moat 1. It also functions as a common electrode for the p-type layer 6. The nail, P'IN□ photodiode D, is formed by an amorphous silicone. and light shielding film 4
Since it is performed after the formation of □, it is undesirable because it is formed at a high temperature that deteriorates the characteristics of the internal circuit A. Also, the light shielding film 4 is formed after the formation of A! A4 is 500℃ if it is made of wood.
This is because the light-receiving element is formed at a lower temperature than this, since melting etc. will occur at a temperature higher than this. -What about temorphous silicon?
