Patent ID: 8435823

Claim:
A method of manufacturing a back-illuminated solid-state imaging device, comprising: preparing an element formation substrate where a first-conductivity-type semiconductor layer has been formed on a semiconductor substrate via a buried insulating film and forming a mask which has apertures corresponding to a pixel pattern on the surface of the semiconductor layer in the element formation substrate; implanting second-conductivity-type impurity ions into the semiconductor layer from the surface of the layer by use of the mask to form second-conductivity-type photoelectric conversion parts serving as the pixels and causing a part into which no ion has been implanted to remain of the first conductivity type as a pixel separation region; forming a signal scanning circuit configured to read an optical signal obtained at the photoelectric conversion parts at the surface of the semiconductor layer after removing the mask; causing a support substrate to adhere to the surface of the semiconductor layer at which the signal scanning circuit has been formed; and removing the semiconductor substrate and buried insulating film from the semiconductor layer after the support substrate has been caused to adhere to the surface.
