Abstract:
1. An apparatus for manufacturing a semiconductor or liquid crystal, having a ceramic holder which is provided inside a reaction chamber to which is supplied a reactive gas, and which holds and heats a material to be treated on a surface thereof, said apparatus comprising: a cylindrical support member one end of which supports the ceramic holder at a portion other than the surface which holds the material to be treated and the other end of which is fixed to a portion of the reaction chamber; a supply tube which opens in the space within the cylindrical support member and supplies an inert gas to the space within the cylindrical support member; an evacuation tube which opens in the space within the cylindrical support member, and an evacuation pump which evacuates the inert gas through the evacuation tube from the space within the cylindrical support member; and a resistive heating element which is embedded in the ceramic holder, said resistive heating element being isolated from an atmosphere within the cylindrical support member.
