PURPOSE: To enhance resistance to separation and package crazing by using heat spray deposition as the adhesion between a heat dissipating member and a substance to be adhered to this heat dissipating member to cover the heat dissipating member. CONSTITUTION: A heat dissipating member 15 is provided with a relatively thin film 23 applied by heat spray coating method, and a coating of nickel - aluminum applied by flame plasma deposition method. The film 23 considerably enhances the adhesion between a molded compound 19 and the heat dissipating member 15. Thus, the separation therebetween hardly occurs. In this method, the adhesion can be enhanced ten or more times, in response to inherent adhesion of the surface of the heat dissipating member to which the film 23 is applied. |
