Abstract:
1. A method of manufacturing a solid-state imaging device, comprising: forming a trench at a position to isolate a plurality of photoelectric conversion elements including an imaging photoelectric conversion element used for imaging of an image and an adjustment photoelectric conversion element used for an image quality adjustment of an imaged image; forming a concave portion at a position to form a light shielding film that shields at least part of subject light incident to the adjustment photoelectric conversion element; coating inner circumferential surfaces of the trench and the concave portion with an insulating film; and burying a light shielding member inside the trench and the concave portion whose inner circumferential surfaces are coated with the insulating film; wherein the concave portion is formed such that an aperture plane is one-sided in a predetermined direction with respect to the light receiving surface of the adjustment photoelectric conversion element used for a focus adjustment by a phase difference detection scheme; and wherein the concave portion is formed at a position to form a light shielding film that shields diagonal half of the light receiving surface of the adjustment photoelectric conversion element.
