Abstract
A photodetector includes a semiconductor substrate having first and second main surfaces opposite to each other. The photodetector includes at least one trench formed in the first main surface and a first anode/cathode region having a first conductivity formed proximate the first main surface and sidewalls of the at least one trench. The photodetector includes a second anode/cathode region proximate the second main surface. The second anode/cathode region has a second conductivity opposite the first conductivity. The at least one trench extends to the second main surface of the semiconductor substrate.
