Patent ID: 7812380

Claim:
A solid-state imaging device comprising: a semiconductor substrate including a first region of a first conductivity type; a signal accumulation region of a second conductivity type which converts light into a signal charge and accumulates the signal charge, said signal accumulation region provided within the first region; a gate electrode provided above the first region; a drain region of the second conductivity type provided on the first region on a side opposite to said signal accumulation region in relation to said gate electrode; an isolation region having insulating properties, which is provided so as to surround a region where said signal accumulation region, said gate electrode, and said drain region are provided; a first conductivity type dopant doping region provided in contact with a side face and a bottom face of said isolation region, said first conductivity type dopant doping region having a higher dopant concentration than the first region; and a second conductivity type dopant doping region provided within the first region, under an end of said gate electrode in a gate width direction and not under a center of said gate electrode in the gate width direction.
