Abstract:
1. A method of fabricating a semiconductor device comprising the steps of: bonding a first semiconductor element on a wiring board in a flip-clip bonding manner; forming a resin peripheral wall on said wiring board in such a manner that the first semiconductor element is surrounded by the resin peripheral wall; filling a space surrounded by the resin peripheral wall with a liquid sealing resin; fixing a back surface of a second semiconductor element on an upper surface of sealing resin; and connecting an electrode provided on a front surface of the second semiconductor element to a segment of wiring on the wiring board of means of a bonding wire after fixing of the second semiconductor element on the sealing resin, wherein said step of fixing the second semiconductor element on the upper surface of the sealing resin is carried out by placing the back surface of the second semiconductor element on the upper surface of the sealing resin before perfect hardening of the sealing resin and after sealing resin becomes hard by a prescribed level.
