Abstract
Disclosed is a semiconductor package having: a semiconductor chip; a package substrate; a wire connected to the semiconductor chip; and an 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. 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 are arranged, and the other surface 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. A heat-transfer member is provided in the fourth area and transmits heat generated by the semiconductor chip to the printed board through the package substrate.
