Abstract:
A semiconductor package comprising:a semiconductor chip;a package substrate composed of ceramic on which the semiconductor chip is mounted;a wire formed on the package substrate and connected to the semiconductor chip; andan electric connection member formed on the package substrate to electrically connect the wire to a printed board when the package substrate is mounted on the printed board,wherein one surface of the package substrate has a first area in which the semiconductor chip is mounted and a second area in which the wire is arranged, and the other surface of the package substrate has a third area which is located in the rear of the second area and in which the electric connection member connects the wire to the printed board and a fourth area which is located in the rear of the first area, andwherein the fourth area has neither a wire nor an electric connection for connecting the package substrate and the printed board, the package substrate between the first area and the fourth area has no inner wire, and a heat-transfer member for transmitting heat generated by the semiconductor chip to the printed board through the package substrate is mounted on said other surface of the package substrate in the fourth area.
