Abstract:
A process for manufacturing a semiconductor device comprising the steps of:providing a sheet of conductive material having first and second surfaces and a thickness; selectively applying an etch resistant material to the second surface of the sheet; forming a mold lock extending upwardly from the first surface of the sheet wherein the mold lock does not form a recess within the first surface of the sheet; attaching a semiconductor die to the first surface of the sheet; forming an electrical connection from the semiconductor die to the mold lock; providing an encapsulating resin overlying the first surface of the sheet to encapsulate the mold lock, semiconductor die and electrical connection; and selectively etching through the thickness of the sheet from the second surface using the etch resistant material as an etch mask to expose the encapsulating resin.
