Abstract:
1. A solid state imaging device comprising: a positive hole accumulation region of a first conductivity within a signal charge accumulation region of a second conductivity, said positive hole accumulation region being between a first portion of the signal charge accumulation region and a second portion of the signal charge accumulation region; a read-out gate region of the first conductivity in physical contact with a region of the first conductivity and a first transfer channel of the second conductivity, said read-out gate region being between said first transfer channel and said first portion of the signal charge accumulation; a gate insulation film between said first portion of the signal charge accumulation region and an edge of a first electrode, wherein along a first direction within a plan view of a layout, said positive hole accumulation region is spaced from said edge of the first electrode by a first offset amount.
