ABSTRACT:
A semiconductor light detecting device comprises a substrate, a first stacked layer of a first conductivity type formed on the substrate by alternately laminating a compound semimetal layer and a compound semiconductor layer repeatedly, a second stacked layer of a second conductivity type formed on the first stacked layer by alternately laminating the compound semimetal layer and the compound semiconductor layer repeatedly, and an isolation region formed by selectively irradiating the first and second stacked layers with an energy beam. A plurality of light detecting elements isolated from each other by the isolation region are formed on the substrate so as to provide the semiconductor light detecting device.
