Semiconductor device and method of manufacturing the same |
| abstract |
In a high power transistor, when the thickness of a semiconductor substrate is set to 200 mm or less, problems such as a decrease in mechanical strength and breakage of an element occur, and as a result, there is a disadvantage that the resistance of the substrate is large. A metal substrate is used as a substrate for a semiconductor device. The metal substrate includes a metal base made of a first metal and a connection metal layer made of a second metal covering the metal base. A substrate having a structure in which a diffusion preventing layer for preventing diffusion of a first metal on a metal layer is obtained. [Selection diagram] Fig. 1 |
