Abstract
Provided herein are approaches for forming an image sensor with increased well depth due to cryogenic ion channeling of ultra-high energy (UHE) ions. In some embodiments, a method may include providing a wafer of a semiconductor device, the semiconductor device including a photoelectric conversion region, and cooling the wafer to a temperature less than −50° C. The method may further include performing an ion implant to the photoelectric conversion region to form a photodiode well after cooling the wafer.
