Abstract
A PIN photodiode having a substrate, a first type electrode layer disposed on the substrate, a first layer of intrinsic material disposed over a portion of the first-type electrode layer, a first type window layer disposed over said intrinsic layer. An island shaped region of intrinsic material is disposed over the window layer and a dielectric layer disposed over the island region and at least the peripheral portion of said island shaped region whereby an opening is formed in the island shaped region. A dopant is diffused through the opening so as to form a PN junction that extends into the first layer of intrinsic material.
