Patent ID: 8120081

Claim:
A solid-state imaging device comprising: an interconnect structure; and a semiconductor substrate provided on the interconnect structure, the semiconductor substrate including: a first-conductivity-type region formed so as to partition a lower portion of the semiconductor substrate into a plurality of regions; and an insulating member made of an insulating material and buried in a region immediately above the first-conductivity-type region, the semiconductor substrate being irradiated with light from its upper surface side; a high-concentration region of a second conductivity type formed in a lower portion of a region partitioned by the first-conductivity-type region and the insulating member; and a low-concentration region of the second conductivity type provided immediately above the high-concentration region and having a lower effective impurity concentration than the high-concentration region, and the insulating member has a lower surface which is located above an interface between the high-concentration region and the low-concentration region.
