Abstract

PURPOSE:To preferably cool generated heat at the normal time even if a thermal load is temporarily increased by sealing wax in a sealed space formed between a cap and a substrate, and further connecting fins between the cap and the substrate. CONSTITUTION:The face of a substrate 2, disposed at opposite side to the face for placing a semiconductor IC chip 1 is thermally connected to a cap 3 with fins 11. With such a configuration, when the chip 1 generates heat, the heat is transferred to the substrate 2. The heat transferred to the substrate 2 is transmitted at one side to the mixture 4 of wax and powder metal, and at the other to the cap 3 through the fins 11. In this case, when the quantity of the generated heat of the chip 1 is abruptly increased, the wax is melted by the heat at that time, the heat is absorbed by the phase change, thereby maintaining the temperature constant. On the other hand, if the generated heat is of the degree not melting the wax, it is transferred to the cap 3 by thermal conduction of the fins 11 and the metal powder, and dissipated through the cap 3.
