    摘要: A photo diode and a signal processing circuit are formed on a silicon substrate. The signal processing circuit comprises a PNP transistor and an NPN transistor. A region of the signal processing circuit on the silicon substrate is covered by an aluminum thin film functioning as a shielding film. A covered distance L(.mu.m) is defined as an overhang of the aluminum thin film from the edge of the PNP transistor, and is determined based on a ratio of a minimum current of the PNP transistor, which induces malfunction in the signal processing circuit under the solar radiation, to a current generated in the circuit element when subjected to the solar radiation without the aluminum thin film.

    摘要: A photoelectric transfer device having a light receiving element and a signal processing circuit are formed in a semiconductor substrate, a silicon oxide film is formed on the light receiving element, a first aluminum thin film is deposited on the silicon substrate, and the first aluminum thin film is patterned to make a wire connected with the signal processing circuit and a protective film placed on the silicon oxide film. Thereafter, an inter-layer insulating film is deposited on the silicon substrate while covering the protective film, a portion of the inter-layer insulating film placed on the protective film is etched and removed, a second aluminum thin film is deposited on the inter-layer insulating film and the protective film, and a portion of the second aluminum thin film placed on the protective film and the protective film are successively etched and removed. Because the inter-layer insulating film placed above the light receiving element is removed, an insulating film placed on the light receiving element is not thinned, so that sensitivity of the photoelectric transfer device can be improved. Also, because the protective film is arranged on the silicon oxide film when the portion of the inter-layer insulating film is etched, the silicon oxide film is not etched, so that a film thickness of the silicon oxide film can be correctly set to a desired value.
