Patent ID: 7271462

Claim:
A solid-state image sensing device comprising an integration of plural pixels, each of which has a light-receiving portion that receives light and generates and accumulates a signal charge, and has the following parts: a semiconductor substrate of the first electroconductive type; a semiconductor layer of the second electroconductive type that is formed on the principal surface of said semiconductor substrate; a gate electrode for pixel selection formed via a gate insulating film on said semiconductor layer; a first semiconductor region of the first electroconductive type that is formed in the outer layer of said semiconductor layer in the light-receiving portion positioned on one side of said gate electrode for pixel selection; a second semiconductor region of the first electroconductive type formed deeper than said first semiconductor region in the outer layer of said semiconductor layer in said light-receiving portion wherein the semiconductor substrate, the semiconductor layer of the second electroconductive type and the second semiconductor region form a vertical transistor; a third semiconductor region of the first electroconductive type formed in the outer layer of said semiconductor layer on the other side of the gate electrode for pixel selection, and containing an impurity of the first electroconductive type and having an impurity concentration higher than that of said first semiconductor region; further comprising: a gate electrode for reset that is formed via a gate insulating film on said semiconductor layer, and a fourth semiconductor region of the second electroconductive type that is formed in the outer layer of said semiconductor layer on one side of said gate electrode for reset; said first semiconductor region is formed in the outer layer of said semiconductor layer on the other side of said gate electrode for reset; said semiconductor layer, said gate electrode for reset, and said fourth semiconductor region form a buried-channel type of transistor for reset, and said signal charge accumulated in said light-receiving portion is evacuated from said light-receiving portion when said transistor for reset operates.
