Abstract
The solid-state imaging device is applicable to a high sensitivity color camera although its structure is as simple as that of a monochromatic camera, and comprises a semiconductor chip in which a large number of pixels are arranged in a matrix form on one surface of a semiconductor substrate, and an optical grating body for separating an incident light into rays of light to allow them to be incident to the pixel trains in one direction on the chip. The optical grating body includes optical gratings arranged at a pitch corresponding to two or three pixels of a pixel train in a direction perpendicular to the above-mentioned one direction, having a fixed inclination relative to the substrate surface, and juxtaposed provided in the above-mentioned one direction, and a supporting surface for supporting the gratings so that they have the above-mentioned fixed inclination.
