ABSTRACT:
A method and crucible for annealing SiC at high temperatures. The crucible is a vessel having a peripheral wall, at least two compartments separated by an inner wall within the peripheral wall and a lid which separates the compartments from the crucible surroundings while providing a passageway between the compartments. The peripheral wall, inner wall and lid are composed of materials capable of withstanding annealing temperatures. The process disposes an SiC wafer in one of the compartments and SiC powder disposed in another of the compartments. The SiC powder is present to hinder SiC wafer decomposition during annealing of the SiC wafer. The crucible is then heated to a temperature sufficient anneal the SiC wafer, preferably after evacuating air and flowing an inert gas in and around the crucible.
