ABSTRACT:
A semiconductor integrated circuit device with a built-in photosensor is provided with a light shielding aluminum film which is formed on a whole surface of the semiconductor integrated circuit device continuously to prevent faulty operation of the semiconductor integrated circuit because of incident light. In order to reduce parasitic capacity generated between a light shielding aluminum film and a wiring for transmitting a high-frequency signal or other elements whereto a high-frequency signal is applied, a light shielding aluminum film is partially removed on the wiring and other elements as well as a photosensor and a pad.
