Abstract:
1. A backside illuminated diode, comprising: a semiconductor substrate of a first conductivity type, having a front surface and a rear surface, said rear surface adapted to receive illumination thereon, and said substrate including at least one structure of a second conductivity type opposite to said first conductivity type, said at least one structure formed adjacent to said front surface, and said semiconductor substrate including first and second portions which are homostructural with one another and which does not have an deposited electrode layer thereon, including the first portion which is unmodified substrate material that is unmodified from an original form of said substrate, and the second portion which is modified substrate material, modified from said original form to form a native conductive electrode layer adapted having a connection that receives a biasing potential thereon and where said biasing is applied to said second portion without being applied through a polysilicon layer.
