SOLID STATE IMAGE PICKUP ELEMENT AND MANUFACTURING METHOD OF THE SAME, AND ELECTRONIC INFORMATION INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a solid state image pickup element which prevents even when a position of a surface high-concentration region for reduction in dark current which composes a light-receiving part fluctuates due to variability in processing, difficulty in reading of signal charges from the light-receiving part to a charge reading region due to the position fluctuation thereby to inhibit increase in a residual image component.SOLUTION: A CCD image sensor which has a plurality of light-receiving parts formed on an n-type epitaxial substrate 2 and reads signal charges obtained by the light-receiving parts by photoelectric conversion of incident light comprises: a light-shielding film 13 formed so as to cover regions other than n-type charge storage regions 4 which compose the light-receiving parts; and surface high-concentration regions 4a which composes the light-receiving parts are positioned with respect to openings 13a in the light-shielding film in a self-alignment manner.
