摘要:
A solid-state imaging device is disclosed. The solid-state imaging device includes: a plurality of photosensitive elements for converting light into electric charge, the plurality of photosensitive elements being arranged in a matrix form; a plurality of first charge transfer portions for transferring the converted electric charge in a first direction, the plurality of first charge transfer portions being formed between the plurality of photosensitive elements arranged along a second direction; a second charge transfer portion for receiving the electric charge from the plurality of first charge transfer portions and for transferring the electric charge in the second direction, the second charge transfer portion being provided at an end of each of the plurality of first charge transfer portions; a plurality of light converging portions for converging the light on each of the plurality of photosensitive elements, the plurality of light converging portions being formed over the plurality of photosensitive elements, respectively; and wherein the plurality of light converging portions are microlenses, each of the microlens having substantially the same curvature in the first and second directions.
