    摘要: An apparatus and method for manufacturing a semiconductor device includes a reaction chamber adapted to exhaust gas therefrom, and a cleaning gas supplying system for introducing cleaning gas containing ClF.sub.3 into the reaction chamber, the system having a plurality of gas blowout holes formed in the flow direction of gas at least in the reaction chamber. The reaction chamber may be a tubular chamber, and the cleaning gas supplying system may be a tube extending from one end to the other end of the reaction chamber along the inner wall or the central axis of the reaction chamber, a plurality of through holes being formed in the side wall of the tube. Damages to the inner surface of the reaction chamber of the semiconductor device manufacturing apparatus can be suppressed and a film attached to the inner wall of the reaction chamber can be removed in a short time.

    摘要: A heating apparatus for use in heating a substrate comprises an electric heater and a power supply part. The electric heater is made up of an approximately columnar body which is made of graphite, and this columnar body has a top with a flat surface part on which the substrate is placed and a pair of legs which extend downwardly from the flat surface part. The legs are defined by an opening in the columnar body. The power supplying part is coupled to the electric heater and supplies a voltage across the legs of the columnar body so that a current flows from one leg to the other, thereby generating heat at the flat surface part to heat the substrate.
