    摘要： A plasma doping method and apparatus in which a prescribed gas is introduced into a vacuum container while being exhausted by a turbomolecular pump as an exhaust apparatus. The pressure in the vacuum container is kept at a prescribed value by a pressure regulating valve. High-frequency electric power of 13.56 MHz is supplied to a coil disposed close to a dielectric window which is opposed to a sample electrode, whereby induction-coupled plasma is generated in the vacuum container. Every time a prescribed number of samples have been processed, a dummy sample is subjected to plasma doping and then to heating. The conditions for processing of a sample are controlled so that the measurement value of the surface sheet resistance becomes equal to a prescribed value, whereby the controllability of the impurity concentration can be increased.
