Patent ID: 8120023

Claim:
A photodiode comprising: a substrate having at least a first side, wherein said first side has an active area located therein, and a second side, wherein said second side comprises a plurality of electrical contacts; each of the plurality of electrical contacts is electrically isolated from each other; within said substrate, a shallow diffused region of a first conductivity type directly under said active area; within said substrate, a deep diffused region of the first conductivity type extending from said shallow area to said second side; within said substrate, at least two deep diffused regions of a second conductivity type extending from said first side to said second side, wherein said deep diffused region of the first conductivity type lies between the two deep diffused regions of the second conductivity type; and wherein each of said deep diffused region of the first conductivity type and the two deep diffused regions of the second conductivity type are in physical contact with said a plurality of electrical contacts.
