摘要: It is an object to prevent functions expected originally from being unexhibited when impurities to be introduced into a solid sample are mixed with each other, and to implement plasma doping with high precision. In order to distinguish impurities which may be mixed from impurities which should not be mixed, first of all, an impurity introducing mechanism of a core is first distinguished. In order to avoid a mixture of the impurities in very small amounts, a mechanism for delivering a semiconductor substrate to be treated and a mechanism for removing a resin material to be formed on the semiconductor substrate are used exclusively.

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.
