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 7):
A method for manufacturing a solid state imaging device, the method comprising:\n a step of forming a first epitaxial layer on a semiconductor substrate; a step of forming a photoelectric conversion region first layer and an element separation region first layer surrounding the photoelectric conversion region first layer on the first epitaxial layer; a step of forming a second epitaxial layer on the first epitaxial layer to cover the photoelectric conversion region first layer and the element separation region first layer; and a step of forming a second photoelectric conversion region second layer on the photoelectric conversion region first layer in the second epitaxial layer and forming an element separation region second layer continuous with the element separation region first layer, wherein\n the photoelectric conversion region first layer and the photoelectric conversion region second layer constitute a photoelectric conversion region over the first epitaxial layer and the second epitaxial layer, and \n the element separation region first layer and the element separation region second layer constitute an element separation region over the first epitaxial layer and the second epitaxial layer.
