With increasing density and improving performance as well as growing function variety of the circuits integrated in a semiconductor chip, the heat dissipating capability of an IC package must be effectively promoted. An IC package based on a simple structure while capable of achieving better heat dissipation is therefore suggested by the present invention. The present invention is applicable to the IC package in which at least a semiconductor unit is located on the same side of substrate as terminals (such as solder balls or cylindrical terminals) are. The basic structure of the IC package comprises an electronic apparatus and a heat dissipater. The electronic apparatus includes a carrier such as a substrate, at least a semiconductor unit such as a chip/die, and at least a cylindrical terminal. The semiconductor unit and the cylindrical terminal attaches in approximately the same direction to the carrier. The heat dissipater includes at least a through-hole for the cylindrical terminal to penetrate, thereby the heat dissipater may be close to the carrier, whereby the IC package provides better heat dissipation without need of larger or more complicated structure.
