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 3):
The solid-state imaging element according to  claim 2 , further comprising:\n a first interlayer insulating film which is formed over the first semiconductor substrate to cover respective upper surfaces of the first light receiving elements; a plurality of first wires which are formed in the first interlayer insulating film; a second interlayer insulating film which is formed under the second semiconductor substrate to cover respective lower surfaces of the second light receiving elements; and a plurality of second wires which are formed in the second interlayer insulating film, wherein an upper surface of the first isolation region is in contact with the first interlayer insulating film, while a lower surface of the second isolation region is in contact with the second interlayer insulating film.
