Patent ID: 7691673

Claim:
A method of manufacturing an electronic parts packaging structure, comprising the steps of: preparing a wiring substrate having a wiring pattern; forming an insulating film having a collective opening portion in a packaging area in which a semiconductor chip is mounted, on the wiring substrate, passing through to a thickness direction and exposing the wiring pattern and having an area bigger than an area of the semiconductor chip; flip-chip mounting a connection terminal of the semiconductor chip on the wiring pattern exposed in the opening portion of the insulating film, the semiconductor chip having the connection terminal on an element formation surface thereof and having a protection film on a backside thereof; filling resin in a gap of a lower side of the semiconductor chip and a gap between a side surface of the semiconductor chip and a side surface of the opening portion of the first insulating film; forming a via hole having a depth reaching the connection terminal by etching a predetermined portion of the semiconductor chip and the protection film on the connection terminal, the via hole passing through the semiconductor chip to thickness direction; and forming an upper wiring pattern connected to the connection terminal through the via hole, on the insulating film and the protection film, wherein an upper surface of the semiconductor chip and an upper surface of the insulating film having the opening portion are set to an almost same height.
