Abstract

PURPOSE: To increase the adhesiveness of In, etc. as well as to reduce the heat resistance by coating In, etc. directly to the heat generation part or the cooling part.
CONSTITUTION: The height H of frame plates 13W14' of basement 12 is adjusted 16 to be identical to the sum of the thickness between cooling substance 2 and In plate 6. Weight 17 is put on the In plate and then heated up in the vacuum furnace. Thus, In is fused and flowed, and weight plate 17 touches the frame plate to block the flow of In. Thus, the thickness of the In film is decided. In this way, an easy and accurate cladding is possible for the layer with a large and uniform thickness via just one layer. And the heat generation parts can be cooled down satisfactorily in such constitution.
