Patent ID: 7585694

Claim:
A manufacturing method of a solid-state imaging device, the manufacturing method comprising: an oxide layer forming step of forming an oxide layer on a semiconductor substrate; an ion implantation step of performing ion implantation through the oxide layer to the semiconductor substrate thereby forming a well in a position corresponding to a charge transfer portion; an insulation layer forming step performed on the oxide layer having undergone the ion implantation step, at least in a position corresponding to the well; before the oxide layer forming step: a preliminary oxide layer forming step of forming a preliminary oxide layer on the semiconductor substrate; and a removal step of removing part of the formed preliminary oxide layer; an amplifier forming step of forming an output amplifier to the semiconductor substrate, the output amplifier being operable to convert to a signal voltage a signal charge outputted from the charge transfer portion and to output the signal voltage to outside, wherein the charge transfer portion includes a vertical charge transfer sub-portion and a horizontal charge transfer sub-portion, and the part of the preliminary oxide layer removed in the removal step corresponds, in position, to the vertical charge transfer sub portion and the output amplifier.
