Patent ID: 7884437

Claim:
A semiconductor device comprising: a semiconductor substrate having, on a top surface of said semiconductor substrate, an imaging region in which a plurality of photoreceptors are arranged, and a peripheral circuit region arranged around the imaging region; a plurality of microlenses formed on the imaging region; a low-refractive-index film having a first surface and a second surface opposite to the first surface, the first surface being disposed on the semiconductor substrate to cover the plurality of microlenses and part of the peripheral circuit region; and a transparent substrate formed on part of the second surface the low-refractive-index film above the imaging region, wherein a through hole is formed in the low-refractive-index film above an amplifier circuit arranged in the peripheral circuit region, and is extended from the first surface to the second surface, and the amplifier circuit is covered by an insulating layer, said insulating layer being exposed through the through hole.
