Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a silicon carbide semiconductor device in which an ohmic electrode can be formed through a low-temperature process without employing impurity doping.  <P>SOLUTION: After an element structure and a surface electrode are formed on the top-surface side of an n<SP>+</SP>-type substrate 1, the reverse surface 1b of the semiconductor substrate having surface roughness (Ra) of ≤10 nm is processed so that (100%-reflectivity-permeability) becomes ≥80% at a wavelength of a laser beam to be irradiated. After a metal thin film 110 is formed on the reverse surface 1b of the semiconductor substrate having been processed so that (100%-reflectivity-permeability) becomes ≥80% at the wavelength of the laser beam to be irradiated, the side of the reverse surface 1b of the n<SP>+</SP>-type substrate 1 is irradiated with laser light to form a drain electrode 11 including a silicide layer 111. Consequently, the silicide layer 111 is formed on the drain electrode 11 in the reverse side of the n<SP>+</SP>-type substrate 1 without subjecting the n<SP>+</SP>-type substrate 1 to high-temperature processing. The drain electrode 11 can be formed as the ohmic electrode through the low-temperature process without using an impurity-doped layer.  <P>COPYRIGHT: (C)2011,JPO&INPIT
