Abstract:
1. A fabrication method of a solid state imaging device, in which the solid state imaging device comprises: a plurality of photoelectric conversion portions on or above a substrate; and color filters on or above the respective photoelectric conversion portions, and each of said plurality of photoelectric conversion portions comprises: a lower electrode on or above the substrate; a photoelectric conversion film on or above the lower electrode; and an upper electrode on or above the photoelectric conversion film, the method comprising: forming said plurality of photoelectric conversion portions; forming a first inorganic material film that protects each of said plurality of photoelectric conversion portions above the upper electrode by using a first method, after forming said plurality of photoelectric conversion portions; forming a second inorganic material film that prevents characteristic deterioration of the photoelectric conversion portion caused by the first method on or above the upper electrode by using a second method other than the first method, after forming said plurality of photoelectric conversion portions and before forming the first inorganic material film; forming a polymeric material film that enhances a function of the first inorganic material film on or above the first inorganic material film, after forming the first inorganic material film; and forming the color filters, after forming the polymeric material film.
