摘要:
A crystal growing apparatus comprises a vacuum vessel (10), a heating lamp (12), a lamp controller (13) for controlling the heating lamp (12), a gas inlet port (14), a flow rate adjuster (15) for adjusting the flow rate of a gas, a pyrometer (19) for measuring the temperature of a substrate, and a gas supply unit (30) for supplying a Si 2 H 6 gas or the like to the vacuum vessel (10). An apparatus for ellipsometric measurement comprises: a light source (20), a polariscope (21), a modulator (22), an analyzer (24), a spectroscope/detector unit (25), and an analysis control unit (26) for calculating Ψ, Δ. In removing a chemical oxide film on the substrate therefrom, in-situ ellipsometric measurement allows a discrimination between a phase 1 during which a surface of the substrate is covered with the oxide film and a phase 2 during which the surface of the substrate is partially exposed so that the supply of gas suitable for the individual phases is performed and halted.
