Abstract: In one form, a process of manufacturing an avalanche photodiode includes forming an insulating layer over an active region of a semiconductor substrate. A shallow terminal of the avalanche photodiode is defined using a first patterned mask. A first dopant is implanted through the first patterned mask and the insulating layer to form the shallow terminal. The first patterned mask is removed. A deep terminal of the avalanche photodiode is defined using second patterned mask. A second dopant is implanted through the second patterned mask and insulating layer to form the deep terminal of the avalanche photodiode. A respective terminal of at least one of the shallow terminal and the deep terminal is defined using a respective patterned mask that forms at least two regions that are spatially separated from each other with no implanted structure located in a space therebetween.
