Abstract
A solid-state imaging device has a sensing region, a pad region and a peripheral region between the sensing region and the pad region. The solid-state imaging device includes a plurality of photoelectric conversion elements formed in a semiconductor substrate and disposed in the sensing region, and a bond pad disposed on the semiconductor substrate and in the pad region. The solid-state imaging device further includes a microlens layer disposed above the semiconductor substrate. The microlens layer includes a microlens array in the sensing region and a first dummy structure in the pad region. The first dummy structure includes a plurality of first microlens elements disposed to surround an area of the bond pad. Moreover, the solid-state imaging device includes a passivation film conformally formed on a top surface of the microlens layer.
