Patent ID: 7550814

Claim:
A solid-state imaging device, comprising: a plurality of photosensitive cells, each having a photodiode, arranged on a semiconductor substrate in a matrix; and a peripheral driving circuit that has a plurality of transistors formed on the semiconductor substrate and is configured to drive the plurality of photosensitive cells, the plurality of transistors including a first transistor and a second transistor, the first transistor having a first diffusion layer as a source or a drain where a signal potential corresponding to a signal charge generated by the photodiode is transmitted and held, and the second transistor having a second diffusion layer as a source and a drain where the signal potential is not transmitted, wherein a first edge interval as a distance between an edge of a metal silicide layer formed on a surface of the first diffusion layer and an edge of a gate electrode in the first transistor is larger than a second edge interval as a distance between an edge of a metal silicide layer formed on a surface of the second diffusion layer and an edge of a gate electrode in the second transistor.
