Abstract:
In a solid state imaging device having a plurality of pixels arranged in a matrix on a substrate, each of the plurality of pixels includes a photoelectric conversion region and an element separation region separating the photoelectric conversion region. The substrate includes a semiconductor substrate, a first epitaxial layer formed on the semiconductor substrate, and a second epitaxial layer formed on the first epitaxial layer. The photoelectric conversion region and the element separation region are formed over the first epitaxial layer and the second epitaxial layer.

Claim (Index 3):
The solid state imaging device of  claim 1 , wherein\n an impurity concentration of a part of the photoelectric conversion region provided in the second epitaxial layer is equal to or higher than an impurity concentration of a part of the photoelectric conversion region provided in the first epitaxial layer.
