Abstract:
An offset spacer film (OSS) is formed on a side wall surface of a gate electrode (NLGE, PLGE) to cover a region in which a photo diode (PD) is disposed. Next, an extension region (LNLD, LPLD) is formed using the offset spacer film and the like as an implantation mask. Next, process is provided to remove the offset spacer film covering the region in which the photo diode is disposed. Next, a sidewall insulating film (SWI) is formed on the side wall surface of the gate electrode. Next, a source-drain region (HPDF, LPDF, HNDF, LNDF) is formed using the sidewall insulating film and the like as an implantation mask.

Claim (Index 15):
The method for manufacturing the image capturing device according to  claim 14 , wherein\n in the step (i), the offset spacers are removed by performing the wet etching process; and the method further comprises, after the step (i), the steps of: (j) forming a second insulating film so as to cover the pixel region and the peripheral region; (k) forming a second resist pattern over the second insulating film so as to cover the photoelectric conversion region; (l) performing anisotropic etching of the second insulating film to form respective sidewall spacers on the opposite side surfaces of the first peripheral gate electrode; (m) removing the second resist pattern; (n) after the step (m), forming source-drain regions in the peripheral region on the opposite side surface sides of the first peripheral gate electrode by implanting an impurity of a predetermined conductivity type using the first peripheral gate electrode and the sidewall spacers as an implantation mask.
