Claim:
1. A semiconductor device comprising: a wiring board comprising: a semiconductor chip located over the chip mounting surface of the wiring board, comprising: a plurality of wires for coupling the electrode pads over the wiring board and the bonding pads of the semiconductor chip respectively; a first spacer located between the chip mounting surface of the wiring board and the back surface of the semiconductor chip, having an upper surface facing the semiconductor chip and a lower surface facing the wiring board; a heat slug located over the main surface of the semiconductor chip; and a sealing member covering the chip mounting surface of the wiring board, the semiconductor chip, the wires, the first spacer, and the heat slug, wherein the sealing member lies between the main surface of the semiconductor chip and the heat slug, wherein a first adhesive layer is formed between the lower surface of the spacer and the chip mounting surface of wiring board, wherein a second adhesive layer is formed between the upper surface of the spacer and the back surface of the semiconductor chip, wherein the spacer is devoid of adhesiveness, and wherein the semiconductor chip is not overlapped with another semiconductor chip, as projected in a plan view.
