Abstract
A semiconductor light receiving device is provided, which comprises a semiconductor substrate, a collector region, a base region, and an emitter 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 being electrically connected to the emitter 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 and being electrically connected to the emitter region. 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.
