Abstract: A method and apparatus for forming a backside contact, electrical and/or thermal, for die encapsulated in a semiconductor device package are provided. Die of varying thicknesses can be accommodated within the semiconductor device package. Embodiments of the present invention provide a conductive pedestal coupled to a backside contact of a die, where the coupling is performed prior to encapsulating the die within the package. In addition, conductive pedestals coupled to varying die within a semiconductor device package are of such a thickness that each conductive pedestal can be exposed on the back side of the package without exposing or damaging the backside of any encapsulated die. Embodiments of the present invention provide for the conductive pedestals being made of electrically or thermally conductive material and coupled to the device die contact using an electrically and/or thermally conductive adhesive.
