Abstract
A photodiode device and methods of manufacturing the same are provided. The photodiode device comprises a light absorption layer defining a light-facing side and a back-light side; a via passing through the absorption layer, the via defining a side wall and a bottom surface; a conformal isolation layer covering the side wall and the bottom surface; a first patterned conductive layer disposed on the back-light side, the first patterned conductive layer having a first portion covering a first portion of the conformation isolation layer; a second patterned conductive layer disposed on the light-facing side of the absorption layer; and an opening through the conformal isolation layer, wherein the opening is filled with the second patterned conductive layer such that the second patterned conductive layer is connected with the first portion of the first patterned conductive layer.
