Patent ID: 8558338

Claim:
A solid-state imaging device comprising: a semiconductor substrate; a ground layer formed on the semiconductor substrate and having an upper surface corresponding to a pixel region, the upper surface being lower than an upper surface corresponding to a peripheral circuit region; a plurality of color filters disposed two-dimensionally on the upper surface of the ground layer corresponding to the pixel region; and a partition wall provided between the color filters, wherein an occupied area of the partition wall provided in an outer portion of the pixel region adjacent to the peripheral circuit region is smaller than that of the partition wall provided in a central portion of the pixel region in a section which is orthogonal to the upper surface of the ground layer corresponding to the pixel region, wherein the outer portion of the pixel region is extended along the peripheral circuit region and has a width which is equal to or greater than 1 micrometer and is equal to or smaller than 100 micrometers.
