Abstract:
1. A solid-state image pickup device comprising: a first photoelectric converter which is formed on a semiconductor substrate and which coverts incident light to a signal charge; a transfer transistor which is formed on the semiconductor substrate and which transfers the signal charge converted by the first photoelectric converter; a first floating diffusion layer which is formed on the semiconductor substrate and which stores the signal charge transferred by the transfer transistor; a reset transistor which is formed on the semiconductor substrate and which resets the signal charge stored in the first floating diffusion layer; and an amplifier transistor which is formed on the semiconductor substrate and which amplifies the signal charge stored in the first floating diffusion layer, wherein a source region and a drain region of the reset transistor, and its channel region between the source region and the drain region are formed in an L-shape on the semiconductor substrate.
