Abstract:
1. A film forming apparatus comprising: a processing chamber inside which a vacuum space is maintained and to which a film forming gas is supplied; a substrate supporting unit, which is disposed inside the processing chamber, for holding a substrate; and a heater which is made of a compound material, wherein the material includes Ta, Mo or W as a high-melting point metal and carbon, and wherein the heater is disposed inside the processing chamber to heat the substrate; a heat insulating member installed between the substrate supporting unit and the processing chamber and between the heater and the processing chamber; and a heat insulating member supporting structure made of quartz and formed outside the heat insulating member so as to cover the heat insulating member, wherein the heat insulating member supporting structure separates the vacuum space into a film forming gas supply space where the heat insulating member and the substrate supporting unit are installed and a heat insulating space defined between the processing chamber and the heat insulating member, wherein the heater includes a main body and a heating element embedded in the main body, and wherein the main body is made of the compound material.
