Abstract:
A method of manufacturing a solid-state image sensor, includes forming a first isolation region of a first conductivity type in a semiconductor layer having first and second surfaces, the forming the first isolation region including first implantation for implanting ions into the semiconductor layer through the first surface, forming charge accumulation regions of a second conductivity type in the semiconductor layer, performing first annealing, forming an interconnection on a side of the first surface of the semiconductor layer after the first annealing, and forming a second isolation region of the first conductivity type in the semiconductor layer, the forming the second isolation region including second implantation for implanting ions into the semiconductor layer through the second surface. The first and second isolation regions are arranged between the adjacent charge accumulation regions.

Claim (Index 16):
A solid-state image sensor which includes a semiconductor layer having a first surface and a second surface, comprising:\n charge accumulation region pairs which are arranged between the first surface and the second surface, one of the charge accumulation region pairs including charge accumulation regions to accumulate a charge; microlenses which are arranged on a side of the second surface so that one of the microlenses is assigned to the one of the charge accumulation region pairs; a first isolation portion which is arranged between the charge accumulation regions of the one of the charge accumulation region pairs, the first isolation portion including a first isolation region extending from the second surface toward the first surface; and a second isolation portion which is arranged between the charge accumulation region pairs, the second isolation portion including a second isolation region extending from the second surface toward the first surface, wherein a depth, from the second surface, of the first isolation region is smaller than a depth, from the second surface, of the second isolation region.
