Claim:
1. A method of manufacturing an electronic device, the method comprising: providing a semiconductor die comprising a conductive pad, a die dielectric layer, and an aperture in the die dielectric layer through which the conductive pad is exposed; forming a conductive post on the semiconductor die and electrically connected to the conductive pad, where the conductive post comprises a bottom post end, a top post end surface opposite the bottom post end, and a side post surface between the bottom post end and the top post end surface; applying a film to the top post end surface and at least an upper end portion of the side post surface; after said applying a film, forming an encapsulating layer between the applied film and the semiconductor die; after said forming an encapsulating layer, removing the film; and forming a conductive interconnection structure on the top post end surface.
