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.

Abstract: A package structure of photodiode and a forming method of the same are provided. The method includes providing a heat-dissipation plate; placing a circuit board on the heat-dissipation plate, the circuit board having an opening exposing a top surface of the heat-dissipation plate and a first contact pad located on a peripheral area of the opening; placing a carrier with a metal cladding surface into the opening, the carrier connecting the top surface of the heat-dissipation plate; placing a photodiode chip on the carrier wherein the bottom area of the photodiode chip is less than the metal cladding surface such that a portion of the metal cladding surface is exposed; and electrically connecting the exposed metal cladding surface to the first contact pad.
