Abstract
In a back-illuminated solid-state image pickup device including a semiconductor substratehaving a light incident surface at a back surface side and a charge transfer electrodedisposed at a light detection surface at an opposite side of the semiconductor substratewith respect to the light incident surface, the light detection surface has an uneven surface. By the light detection surface having the uneven surface, etaloning is suppressed because lights reflected by the uneven surface have scattered phase differences with respect to a phase of incident light and resulting interfering lights offset each other. A high quality image can thus be acquired by the back-illuminated solid-state image pickup device.
