Abstract:
A solid-state image sensor comprising:a first-conductivity-type semiconductor layer with a surface; a second-conductivity-type first region provided in said semiconductor layer, constituting a photo-electric conversion section together with said semiconductor layer to store photoelectrically converted signal charges, and having a first end and a second end opposite to each other in one direction along said surface of said semiconductor layer; a gate electrode insulatively provided above said surface of said semiconductor layer so as to be adjacent to said second end of said first region, having a first end and second end opposite to each other in said one direction along said surface of said semiconductor layer, said first end of said gate electrode being offset from a line perpendicular to said surface of said semiconductor layer and passing through said second end of said first region, and positioned on said surface of said semiconductor layer in a part other than that above said first region; a second-conductivity-type second region provided on an upper part of said first region so as to be in contact with said first region, having a first end and a second end opposite to each other in said one direction along said surface of said semiconductor layer; and a second-conductivity-type third region adjacent to said second end of said gate electrode, provided on said surface of said semiconductor layer opposite to said first region, and serving as a drain region.
