Document Type and Number:
Japanese Patent JP5971106
Kind Code:
B2
Abstract:
An optical sensor has a semiconductor substrate, an insulation film formed on the semiconductor substrate, a light receiving part formed on the semiconductor substrate, and an electrode formed on the semiconductor substrate through the insulation film. The light receiving part has a light receiving element which changes light into electric charge, and a reset element which discharges the electric charge accumulated in the light receiving element. The electrode has a first electrode applying a control voltage to the reset element. The first electrode has a light shielding property. The first electrode defines a shape of a light receiving surface of the light receiving element.
