Abstract
A solid-state imaging device has a plurality of light receiving elements formed in a semiconductor substrate. Signal electric charges generated by light incident upon the light receiving elements and stored in the individual light receiving elements are sequentially read out through signal lines by scanning a plurality of switches. Each of the switches includes a series connection of a first MOS transistor switching element formed in the semiconductor substrate and a second MOS transistor formed in a semiconductor provided above the semiconductor substrate through an insulator. The first switching element is disposed on the side of the light receiving element and the second switching element is disposed on the side of the signal output terminal.
