Semiconductor light receiving device and electronic apparatus incorporating the same

A semiconductor light receiving device comprising:

• a semiconductor substrate;
• a collector region on the semiconductor substrate;
• a base region embedded in the collector region and exposed from a surface of the collector region, wherein the base region serves as a light receiving region;
• an emitter region embedded in the base region and exposed from a surface of the base region;
• an insulating film covering the surface of the collector region, the base region, and the emitter region;
• a first metal line on the insulating film at a position corresponding to the base region;
• and
• a second metal line on the insulating film at a position corresponding to a junction portion of the base region and the collector region,
• wherein the first metal line has a sloped surface such that incident light falling on the first metal line is reflected and directed toward the surface of the base region and is covered with a protection film,
• wherein the protection film is made of a metal film.
