Abstract
PURPOSE: To improve sensitivity to a short-wavelength photo signal by exposing the pn junction part of a photo diode on the surface of a main semiconductor body of a unidirectional conduction type.
CONSTITUTION: Applying a positive voltage to storage electrode 24 forms a depletion region at the opposite pn junction part via insulating layer 24. The depletion layer under storage electrode 29 is stored with signal electron flux and only the depletion layer in photosensitive element 18 serves as a photoelectric conversion part. Part of the photosensitive element surface is covered with n-type impurity layer 18a to expose pn junction part 18c on the photosensitive element surface. In this structure, the pn-junction depletion region resides on the surface of the photosensitive element with much signal charge accumulated, thereby suppressing a light loss at the time of a short wavlelength.
