Abstract

The subject of the application is a method for manufacturing ohmic contacts for silicon carbide, which is characterized in that a silicon carbide substrate is exposed to a laser beam with a wavelength of 355 nm (UV laser) to 1064 nm (IR laser) and an energy density of 10 J / cm2 to 50 J / cm2, with a single pulse duration of 10 ns to 50 ns, a pulse frequency of 10 kHz to 100 kHz, and the number of repetitions is from 1 to 30, and a metallic layer is subsequently applied to the modified substrate.
