Patent ID: 7157759

Claim:
A solid-state imaging device comprising: a semiconductor substrate; a plurality of photoelectric converting regions which are arranged on the semiconductor substrate, wherein each of said plurality of photoelectric converting regions includes (1) a plurality of first photoelectric converting regions which are arranged on the semiconductor substrate in a row direction and a column direction that is perpendicular to the row direction and (2) a plurality of second photoelectric converting regions which are arranged on the semiconductor substrate in the row direction and the column direction, each of said plurality of second photoelectric converting regions comprising an opening; and a plurality of microlenses, each of which being formed above and covering each of the first photoelectric converting regions, wherein each of said plurality of second photoelectric converting regions is placed between ones of the microlenses which cover adjacent ones of the first photoelectric converting regions, respectively, a first length in a first direction with respect to a distance from a center of the opening to an edge of the opening of each of the second photoelectric converting regions is longer than a second length in a second direction with respect to the distance from the center of the corresponding opening to the edge of the corresponding opening of each of the second photoelectric converting regions, the first direction is a direction along which, among directions of incidence in a plan view of light that is incident on the second photoelectric converting regions, the light is blocked by a highest degree by the microlenses, and the second direction is a direction along which, among directions of incidence in a plan view of light that is obliquely incident on the second photoelectric converting regions, the light is blocked by a lowest degree by the microlenses.
