ABSTRACT:
A solid-state imaging device has a plurality of photodetector elements arranged on a substrate for photoelectrically converting incident light into signal charges, storing the signal charges, and producing an output signal voltage depending on the amount of the stored signal charges. Element-separating electrodes electrically separate adjacent ones of the photodetector elements from each other. Each of the photodetector elements has a control electrode and a gate insulating film below the control electrode. The gate insulating film has a film thickness varying in the width direction of a channel of the gate insulating film.
