Patent ID: 8349640

Claim:
A method of manufacturing a solid-state image sensor in which a plurality of pixels are formed on a semiconductor substrate, each pixel having a photoelectric converter including an accumulation region where charges are accumulated, and a transfer gate forming a channel to transfer the charges accumulated in the accumulation region to a charge-voltage converter, the accumulation region extending under a corresponding transfer gate, the plurality of pixels being configured to include a plurality of pixel groups, each pixel group including N adjacent pixels (N is an integer of not less than 2), and the channels of the N adjacent pixels, in each pixel group, being configured to transfer the charges of the N adjacent pixels away from each other, the method comprising: a step of forming a resist pattern having one opening corresponding to each pixel group; and a step of forming a charge accumulation region for each of the N adjacent pixels by implanting ions into the semiconductor substrate through the one opening of the resist pattern along N ion implantation directions so as to implant the ions under the transfer gate of each of the N adjacent pixels.
