Classification: CPC H | IPC H

Claim 17:
18. A method of manufacturing an integrated circuit, the method comprising:
forming a photodetection region of the integrated circuit; and
forming a charge storage region and/or a drain region of the integrated circuit, wherein the photodetection region is formed to induce an intrinsic electric field in a first direction from the photodetection region to the charge storage region and/or the drain region at least in part by:
depositing a mask on at least a portion of the photodetection region; and
removing at least a portion of the mask to create an opening having a first end and a second end,
wherein the first end is spaced from the second end in the first direction, and
wherein the opening is wider at the first end than at the second end.
