Abstract:
A method for manufacturing a semiconductor package. A mold-releasing film 21 is disposed on a surface of a cavity 14 to be filled with a thermosetting resin 27 for manufacturing a package in a mold 11 with an element 25 to be packaged installed therein, and then the thermosetting resin 27 is filled into the mold 11. In this case, as the mold-releasing film 21, a laminate film is used in which a base material film disposed on the cavity 14 surface side and a peeling resin disposed on the thermosetting resin side are laminated. As the base material film, an oriented polyester film having two or more melting points not lower than a mold setting temperature is used.
