Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate having a light sensing surface and a non-light sensing surface; a plurality of photoelectric conversion portions each provided to correspond to each of a plurality of pixels in the semiconductor substrate and receiving incident light through the light sensing surface; a pixel separation portion that is embedded into a trench provided on a side portion of the photoelectric conversion portion and electrically separates the plurality of pixels in a side of an incident surface of the semiconductor substrate into which the incident light enters, wherein the pixel separation portion is formed by an insulation material which absorbs the incident light entering the light sensing surface; a wiring layer provided on the non-light sensing surface of the semiconductor substrate; a silicon oxide insulating film with a light sensing surface and a non-light sensing surface, wherein both the light sensing surface and the non-light sensing surface are entirely planar; a substantially transparent planarized film disposed on at least a portion of the light sensing surface of the silicon oxide insulating film; and a light shielding film with a light incident surface and a non-light incident surface, wherein the light shielding film is disposed between the silicon oxide insulating film and the substantially transparent planarized film, and wherein the non-light sensing surface of the light shielding film is in direct contact with at least a portion of the light sensing surface of the silicon oxide insulating film.
