Title: Semiconductor device
Inventor: MITSUMOTO KAZUFUMI
IPC: H01L23/34
Filed: 1991-10-25
Abstract: PURPOSE:To improve the thermal diffusion efficiency of a semiconductor device so as to increase the degree of freedom at the time of circuit design by forming a thermal diffusion section on the surface of a semiconductor element on the side opposite to the substrate. CONSTITUTION:A semiconductor element S is provided with a thermal diffusion member 1 on its substrate 6 with an insulating film 2 between. The member 1 is formed by patterning an Al material etc., to a desired shape by a photo- etching process after the Al material is stuck on the entire surface of the insulating film 2 by vapor deposition, sputtering, etc. Since the insulating film 2 is formed by using an atmospheric-pressure nitride film SiNx and the film 2 can be processed at a low temperature, the material forming the electrodes does not receive any adverse influence at the time of forming the film 2 even when the electrodes are form before the film 2. Since heat sinks can be formed on both surfaces of the semiconductor element S, the heat resistance of this semiconductor device can be improved and, at the same time, the circuit designing efficiency can be improved.
