Abstract:
In a solid-state imaging element having two or more photodiodes stacked in a vertical direction in each of pixels, electrons are prevented from moving between the respective photodiodes of the pixels adjacent to each other. The solid-state imaging element is formed by joining together a back surface of a first semiconductor wafer including one of the photodiodes and a wiring layer and a back surface of a second semiconductor wafer including another of the photodiodes and a wiring layer. By forming a first isolation region extending through a first semiconductor substrate forming the first semiconductor wafer and a second isolation region extending through a second semiconductor substrate forming the second semiconductor wafer, the photodiodes of one of the pixels are isolated from another of the pixels.

Claim (Index 1):
A solid-state imaging element, comprising:\n a plurality of pixels arranged in plan view; a first semiconductor substrate and a second semiconductor substrate which are stacked; a first insulating film which is interposed between the first semiconductor substrate and the second semiconductor substrate and in contact with a lower surface of the first semiconductor substrate and with an upper surface of the second semiconductor substrate; a first light receiving element which is formed in the first semiconductor substrate in each of the pixels; a second light receiving element which is formed in the second semiconductor substrate in each of the pixels; a first isolation region which extends through the first semiconductor substrate from an upper surface thereof to the lower surface thereof to isolate the respective first light receiving elements formed in the pixels adjacent to each other; and a second isolation region which extends through the second semiconductor substrate from the upper surface thereof to a lower surface thereof to isolate the respective second light receiving elements formed in the pixels adjacent to each other.
