Abstract
The present application is directed to novel front side illuminated, back side contact photodiodes and arrays thereof. In one embodiment, the photodiode has a substrate with at least a first and a second side and a plurality of electrical contacts physically confined to the second side. The electrical contacts are in electrical communication with the first side through a doped region of a first type and a doped region of a second type, each of the regions substantially extending from the first side through to the second side. In another embodiment, the photodiode includes a wafer with at least a first and a second side; and a plurality of electrical contacts physically confined to the second side, where the electrical contacts are in electrical communication with the first side through a diffusion of a p+region through the wafer and a diffusion of an n+region through the wafer.
