摘要： In a plasma doping device according to the invention, a vacuum chamber is evacuated with a turbo-molecular pump as an exhaust device via a exhaust port while a predetermined gas is being introduced from a gas supply device in order to maintain the inside of the vacuum chamber to a predetermined pressure with a pressure regulating valve. A high-frequency power of 13.56 MHz is supplied by a high-frequency power source to a coil provided in the vicinity of a dielectric window opposed to a sample electrode to generate inductive-coupling plasma in the vacuum chamber. A high-frequency power source for supplying a high-frequency power to the sample electrode is provided. Uniformity of processing is enhanced by driving a gate shutter and covering a through gate.

摘要： It is intended to provide a plasma doping method and apparatus which are superior in the controllability of the concentration of an impurity that is introduced into a surface layer of a sample.A prescribed gas is introduced into a vacuum container 1 from a gas supply apparatus 2 while being exhausted by a turbomolecular pump 3 as an exhaust apparatus. The pressure in the vacuum container 1 is kept at a prescribed value by a pressure regulating valve 4. High-frequency electric power of 13.56 MHz is supplied from a high-frequency power source 5 to a coil 8 disposed close to a dielectric window 7 which is opposed to a sample electrode 6, whereby induction-coupled plasma is generated in the vacuum container 1. A high-frequency power source 10 for supplying high-frequency electric power to the sample electrode 6 is provided. 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.

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.
