Claim 2:
3. A chemical-vapor-deposition silicon carbide (SIC) bulk having an improved etching characteristic, comprising:
silicon carbide (SIC) manufactured by a chemical vapor deposition method using MTS (methyltrichlorosilane), hydrogen (H2), and nitrogen (N2) gases,
wherein the SIC manufactured by the chemical vapor deposition method is β-SiC (3C-SiC), 6H-SiC is present in the SIC manufactured by the chemical vapor deposition method, five peaks having a reference code of 03-065-0360 and at least one peak having a reference code of 00-049-1428 are confirmed to be present from XRD analysis of the silicon carbide bulk, and a resistance value of the silicon carbide is 1 Ω or less,
wherein an average grain size is about 40 to 100 μm when crystal grains are generated.
