摘要
Samples of 6H-SiC were implanted with Ga+ and Sb+ ions in a wide dose range (10(13) to 10(16) cm(-2)) at various target temperatures (-190 degrees C to 1200 degrees C). Short-time annealing was performed at temperatures from 600 degrees C to 1750 degrees C. The as-implanted and annealed samples were analyzed by means of the RBS-channeling technique, XTEM and optical measurements. The results show that amorphization can be prevented for implantation temperatures greater than or equal to 300 degrees C; from 500 degrees C to 800 degrees C minimum damage concentrations are obtained. Annealing of amorphous layers is quite difficult and non-perfect, no monocrystalline state was found up to temperatures of 1720 degrees C. Weakly damaged layers produced by a low dose (< 1 X 10(14) cm(-2)) at room temperature regrow perfectly at 1200 degrees C. Residual damage after high-dose implantation (greater than or equal to 1 X 10(15) cm(-2)) at elevated temperatures cannot be removed completely by annealing.
