Abstract: An interlayer insulating film is patterned, contact holes are formed, and in the contact holes, a source contact portion forming an ohmic contact with the silicon carbide body is formed. Thereafter, a titanium film and an aluminum wiring layer are continuously formed in this sequence on the interlayer insulating film and the source contact portion. At this time, the thickness of the titanium film is about 1.0 ?m or less. Thereafter, by heat treatment for curing of a passivation film or heat treatment thereafter, the titanium film and the aluminum wiring layer react, generating a TiAl alloy film between the titanium film and the aluminum wiring layer. The thickness of the TiAl alloy film, for example, is kept to about 1 nm to 100 nm; and the TiAl alloy film and the source contact portion do not contact each other.

Abstract: After a titanium nitride film is formed to cover an interlayer insulating film, a first nickel film is formed on a front surface of a silicon carbide base exposed in a contact hole, so as to extend on the titanium nitride film. Next, the silicon carbide base and the first nickel film are reacted by rapid thermal annealing at a temperature of 800 to 1100 degrees C. to form a nickel silicide film that forms an ohmic contact. Grains of the titanium nitride film are enlarged by the rapid thermal annealing, making a grain size of the titanium nitride film 20 nm to 50 nm. Thus, interstices of the grains of the titanium nitride film become smaller than before the rapid thermal annealing or are eliminated, enabling the intrusion of nickel from the first nickel film into the interstices of the columnar grains of the titanium nitride film to be suppressed.
