Patent ID: 7872287

Claim:
A solid-state imaging device unit comprising solid-state imaging devices arranged on a substrate, said solid-state imaging devices each comprising: a signal line formed on the substrate; an island shaped semiconductor placed over said signal line; and a pixel selection line connected to an upper portion of said island shaped semiconductor, said island shaped semiconductor comprising: a first semiconductor layer disposed in a lower portion of said island shaped semiconductor and connected to said signal line; a second semiconductor layer disposed adjacent to an upper side of said first semiconductor layer; a gate connected to said second semiconductor layer via an insulating film; an electric charge accumulator comprising a third semiconductor layer connected to said second semiconductor layer and carrying a quantity of electric charges which varies in response to a light reception; and a fourth semiconductor layer disposed adjacent to an upper side of said second semiconductor layer and said third semiconductor layer and connected to said pixel selection line, wherein said solid-state imaging devices are arranged on said substrate in a honeycomb configuration.
