摘要:
A method and an apparatus for plasma processing which can accurately monitor an ion current applied to the surface of a sample. Predetermined gas is exhausted via an exhaust port by a turbo-molecular pump while introducing the gas within the vacuum chamber from a gas supply device, and the pressure within the vacuum chamber is kept at a predetermined value by a pressure regulating valve. A high-frequency power supply for a plasma source supplies a high-frequency power to a coil provided near a dielectric window to generate inductively coupled plasma within the vacuum chamber. A high-frequency power supply for the sample electrode for supplying the high-frequency power to the sample electrode is provided. A matching circuit for the sample electrode and a high-frequency sensor are provided between the sample electrode high-frequency power supply and the sample electrode. An ion current applied to the surface of a sample can be accurately monitored buy using the high-frequency sensor and an arithmetic device.
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.

A method for introducing impurities includes a step for forming an amorphous layer at a surface of a semiconductor substrate, and a step for forming a shallow impurity-introducing layer at the semiconductor substrate which has been made amorphous, and an apparatus used therefore. Particularly, the step for forming the amorphous layer is a step for irradiating plasma to the surface of the semiconductor substrate, and the step for forming the shallow impurity-introducing layer is a step for introducing impurities into the surface which has been made amorphous.

The invention provides a method of doping impurities that includes a step of doping impurities in a solid base substance by using a plasma doping method, a step of forming a light antireflection layer that functions to reduce light reflection on the surface of the solid base substance, and a step of performing annealing by light radiation. According to the method, it is possible to reduce the reflectance of light radiated during annealing, to efficiently apply energy an impurity doped layer, to improve activation efficiency, to prevent diffusion, and to reduce sheet resistance of the impurity doped layer.

A container is provided for storing a lithographic printing mask. A first container section is formed of a sturdy material which defines a central inner recess area that is shaped to house a mask and to hold outer edges of a mask without touching a pattern on the mask. A second identical container section is placed against the first container section with a mask housed within recesses of, both to form a container which has a common pressure level all around and therein. A higher pressure level is then applied outside the container causes the first and second sections of the container to be held together. To remove the mask from the container, the pressure outside the container is reduced to substantially the pressure level inside the container and the first and second sections are pulled apart.
摘要:
A process for preparing pure antihistamine tannate compositions. The antihistamine in the form of its free base is contacted with tannic acid in the presence of water for a period of time of about 5 minutes to 4 hours and at a maximum temperature such that not more than about 5 wt. % of the antihistamine tannate will be decomposed. Water is removed from the antihistamine tannate by freeze-drying.
