Abstract
A solid-state imaging device comprising a semiconductor substrate; a logic circuit region having a first gate electrode; a pixel region having a plurality of pixel units, each which includes at least one second gate electrode; a first gate insulating film forming between the first gate electrode in the logic circuit region and the semiconductor substrate; a second gate insulating film forming between the second gate electrode in the pixel region and the semiconductor substrate; a first insulating layer covering the first gate electrode and the second gate electrode; and an offset spacer on a sidewall of the first gate electrode being formed by etch back of the first insulating layer on the first gate electrode.
