Patent ID: 7879705

Claim:
A method of manufacturing a semiconductor device comprising a SiC substrate and an electrode formed on the SiC substrate, the method comprising: forming a Ti-layer on a surface of the SiC substrate; forming an Al-layer on a surface of the Ti-layer; maintaining the SiC substrate having the Ti-layer and the Al-layer at a temperature that is higher than or equal to a first temperature which is the minimum temperature of a temperature zone at which the Ti reacts with the Al to form Al 3 Ti, and lower than a second temperature which is the minimum temperature of a temperature zone at which the Al 3 Ti reacts with the SiC to form Ti 3 SiC 2 until all the Ti in the Ti-layer has reacted with the Al, so that an Al 3 Ti-layer is formed on the surface of the SiC substrate; and further heating the SiC substrate having the Al 3 Ti-layer to a temperature that is higher than the second temperature so that the SiC substrate reacts with Al 3 Ti of the Al 3 Ti-layer to form a Ti 3 SiC 2 -layer on the surface of the SiC substrate.
