摘要
The damage production and annealing of 6H-SiC implanted with Ga+ and Sb+ in the temperature region 80-1473 K are investigated by means of the RBS/channelling technique and TEM analysis. For implantation temperatures T-I less than or equal to 473 K amorphous layers are produced at doses ranging between 1 x 10(14) and 3 x 10(14) cm(-2). For T-I greater than or equal to 573 K non-amorphous damaged layers are created consisting of a nearly perfect crystalline thin surface layer and a broad damage band the structure of which depends on the implantation temperature. The annealing results indicate that amorphous layers can hardly be sufficiently annealed by RTA for temperatures up to T-a = 2000 K, whereas weakly damaged layers can be more easily annealed.
