Abstract:
1. An apparatus for manufacturing a semiconductor or liquid crystal, the apparatus comprising: a reaction chamber to which is supplied a reactive gas; a ceramic holder, within the reaction chamber, which holds a material to be treated on a surface thereof and which is heated by a resistive heating element embedded therein; and a cylindrical support member, within the reaction chamber, comprising a first end which supports the ceramic holder at a surface other than a surface for holding the material to be treated, and a second end which is fixed to a portion of the reaction chamber, wherein the first end of the cylindrical support member and the ceramic holder are hermetically bonded, the second end side of the cylindrical support member is hermetically sealed by a sealing material disposed within the cylindrical support member, and the space within the cylindrical support member defined by the ceramic holder and the sealed portion on the second end side depressurized either to vacuum or to a reduced-pressure atmosphere of an inert gas.
