Abstract
A solid-state imaging device includes: a photodiode formed to be segmented with respect to each pixel in a pixel area in which plural pixels are integrated on a light receiving surface of a semiconductor substrate; an insulator film formed on the semiconductor substrate to cover the photodiode; a recessed part formed with respect to each of the pixels in the insulator film in an upper part of the photodiode; a first light transmission layer of a siloxane resin formed to fill the recessed part and configure an optical waveguide in the pixel area; a second light transmission layer formed to configure an on-chip lens with respect to each of the pixels in the pixel area; and a guard ring formed to surround an outer circumference of the pixel area to partition an inner area containing the pixel area and an outer dicing area.
