Abstract

PURPOSE:To improve a solid-state image sensing plate in sensitivity to a blue light and increase its sensitivity to light, by a method wherein the depth of a junction surface is made shallow and deep alternately in the light-receiving part. CONSTITUTION:When light 6 is made incident on the light-receiving part of a solid- state image sensing plate having a junction surface J provided with shallow portions and deep portions alternately, electron-hole pairs generated in the shallow portions by a blue light are absorbed in the shallow junction surface while electron-hole pairs generated in the deep portions by a red light are absorbed in the deep junction surface. Accordingly, it is possible to obtain an effective light-receiving sensitivity distribution with respect to the incident light in a wide wavelength band, from a short wavelength band to a long wavelength band, and because the junction surface has unevenness, the carrier-accumulating capability is increased, so that it is possible to obtain an element which has a large dynamic range as a light-receiving element and resistance to blooming.
