    • PURPOSE: A method for manufacturing a Si template and a SiC single crystallization thin film grown on the Si template are provided to supply a structure in which highly dense defects compensate for each other by an inexpensive wetting process, thereby inexpensively producing a high quality SiC single crystallization thin film. CONSTITUTION: A thermal oxide film is grown in a Si substrate. The thermal oxide film is micro-patterned and regularly arranged to form a square structure. A Si substrate is etched by using a KOH solution. A Si template of a reverse pyramid structure is formed on the surface of the Si substrate. A Si-containing gas and a C-containing gas are supplied to the Si template so that a 3C-SiC thin film(208) can be deposited on the Si template.
