Abstract:
1. A method of assembling a semiconductor device including a heat spreader, the method comprising: attaching the heat spreader to a film; dispensing a mold compound onto the film such that the mold compound at least partially covers the film and the heat spreader; placing the film with the attached heat spreader into a first mold section; providing a substrate having a semiconductor die attached and electrically coupled thereto; attaching the substrate with the attached die to a second mold section; mating the first and second mold sections such that the die is covered by the heat spreader; melting the mold compound at least until the mold compound covers the die and sides of the heat spreader; separating the first and second mold sections, wherein the film adheres to the substrate; and removing the film to expose a top surface of the heat spreader, whereby the semiconductor device is formed.
