Abstract:
1. A method for manufacturing a semiconductor device, comprising the steps of: (a) mounting a semiconductor chip over a first surface of a wiring board; (b) coupling a plurality of electrodes formed at the wiring board and a plurality of bonding pads formed at the semiconductor chip by a plurality of wires respectively; (c) sealing the semiconductor chip mounted over the first surface of the wiring board with a resin; and (d) applying solder paste onto a second surface opposite to the first surface of the wiring board via a mask thereby to form a plurality of first protruded electrodes, wherein the wiring board prepared before the step (a) is formed with: wherein the step (d) forms the first protruded electrodes in such a manner that they are electrically coupled to the second lands via the first openings defined in the protective film, respectively.
