Image pickup element, method of manufacturing image pickup element, and electronic apparatus

A method of manufacturing an image pickup element, the method comprising

• forming a fixed charge film on a light-receiving surface of a semiconductor substrate that includes a photoelectric conversion section for each pixel and has a pixel separation groove,
• wherein the forming of the fixed charge film includes
• forming a first insulating film to be provided contiguously from the light-receiving surface to a wall surface and a bottom surface of the pixel separation groove, and
• forming a second insulating film to be provided on a part of the first insulating film, the part corresponding to at least the light-receiving surface.

An electronic apparatus provided with an image pickup element, the image pickup element comprising:

• a semiconductor substrate including a photoelectric conversion section for each pixel;
• a pixel separation groove provided in the semiconductor substrate;
• and
• a fixed charge film provided on a light-receiving surface side of the semiconductor substrate,
• wherein the fixed charge film includes a first insulating film and a second insulating film, the first insulating film being provided contiguously from the light-receiving surface to a wall surface and a bottom surface of the pixel separation groove, and the second insulating film being provided on a part of the first insulating film, the part corresponding to at least the light-receiving surface.
