Title: Semiconductor package
Inventor: ISHIZUKA MASARU
IPC: H01L23/427
Filed: 1988-03-30
Abstract: PURPOSE:To improve cooling efficiency and to realize substantial reduction in size and weight by bringing a mixture of wax and electric insulator into direct contact with a semiconductor chip. CONSTITUTION:A fin 15 is provided in projection to a surface of a substrate 2 whereon a semiconductor chip 1 is mounted, and a mixture 14 of wax and electric insulator is sealed into an air-tight space which is shaped by a brazed cap 3 and the surface. A fin 11 forms a projection on the mounting surface of the semiconductor chip 1 of a ceramic plate, and the electric insulator is powdered AlN or SiC. When the semiconductor chip 1 generates heat, the heat transmitted to the substrate 2 is transmitted to both the fin 15 and the mixture 14 of wax and electric insulator. When the calorific value of the semiconductor chip 1 increases rapidly, the wax melts and heat is absorbed by the phase change heat to keep a fixed temperature. When the calorific value is small not to melt the wax, it is radiated through the cap 3 by heat conduction by an electric insulator. According to this constitution, good cooling efficiency can be acquired in case of both of transient increase of heat load and usual heat generation allowing substantial reduction in size and weight.
