Filed: 1992-12-14
Abstract: PURPOSE:To enable a photodetective element to be enhanced in sensitivity and lessened in noises by a method wherein oxygen is diffused into a semiconductor substrate only through one of its surfaces. CONSTITUTION:Oxygen is diffused into a semiconductor substrate 1 where a photodetective element 18 is formed only through its surface opposite to its predetermined light receiving surface for the formation of an oxygen diffused layer 4. By this process, the active layer of the photodetective element 18 is set lower than 1X10<18>atoms/cm<3> in oxygen concentration in a depthwise direction, and a region other than the active layer is set higher than 1X10<17>atoms/ cm<3> and larger in oxygen concentration than the active layer located above the region. Therefore, a specific oxygen concentration distribution can be realized, wherein oxygen is made to separate out in a region other than the photodetective element 18 to enhance the region in gettering capacity, and oxygen is restrained from separating out in the photodetective element 18 so as to prevent it from deteriorating in sensitivity and increasing in noises. By this setup, a photodetective element 18 can be enhanced in sensitivity and lessened in noise without decreasing a semiconductor element in yield.
