Abstract :
Studied the effect of rapid thermal annealing (RTA) on the parameters of diode structures with Ni-n-SiC-21R(0001) and Ni-n-SiC-21R(0001¯) Schottky barriers. Ohmic contacts to these structures were formed by nickel resistive sputtering onto the substrate (heated up to 300°C) followed with fusion at T = 450°C for 10 min. It was shown that one can, in principle, obtain Ni-n-SiC diode structures (formed at Si- and C-faces of SiC-21R polytype) that are heat-tolerant up to 450°C
