Abstract:
1. A method for deposition of silicon carbide, the method comprising: preparing a silicone carbide wafer in a susceptor; modifying a surface of the silicon carbide wafer; producing an intermediate compound by introducing a reactive raw material into the susceptor; and forming a silicon carbide epitaxial layer, after modifying the surface of the silicon carbide wafer, on the silicone carbide wafer by reacting the intermediate compound with the silicon carbide wafer, wherein modifying a surface of the silicon carbide wafer comprises introducing at least one of a first and a second etching gas into the susceptor, wherein the first etching gas comprises hydrogen chloride (HCl), and wherein the second etching gas comprises at least one of alkane (CnH2n+2, where 1≦n≦3), alkene (CnH2n−2, where 2≦n≦3), and alkyne (CnH2n, where 2≦n≦3).
