Abstract:
1. A manufacturing method of a semiconductor device comprising a semiconductor chip having an internal connection terminal provided thereon, an external connection terminal pad electrically connected to the semiconductor chip, an encapsulation resin encapsulating the semiconductor chip, and a wiring pattern provided between the semiconductor chip and the external connection terminal pad and electrically connected to the semiconductor chip, the method comprising: a metal layer lamination process for sequentially laminating a first metal layer and a second metal layer on a metal plate which constitutes a support plate, a wiring pattern formation process for etching the second metal layer to form the wiring pattern, an insulating resin formation process for forming an insulating resin on the first metal layer so as to cover the wiring pattern, and a semiconductor chip bonding process for pressing the semiconductor chip against the insulating resin to press-bond the internal connection terminal and the wiring pattern so as to flip-chip bond the semiconductor chip to the wiring pattern, wherein the first metal layer is an etching stopper for etching the second metal layer.
