摘要:
A plasma generating method generates plasma in a treating chamber by controlling a high-frequency generating unit to generate a high-frequency signal and by feeding the high-frequency signal to the treating chamber through an impedance matching device. The plasma generating method includes controlling the impedance matching device, when the plasma is generated in the treating chamber, so as to satisfy a preset matching condition, and then controlling the high-frequency generating unit to generate and feed the high-frequency signal of the power generating the plasma, to the treating chamber.

A compact plasma generating apparatus providing high efficiency of plasma excitation is presented. A plasma generating apparatus (100) comprises a microwave generating apparatus (10) for generating microwaves, a coaxial waveguide (20) having a coaxial structure comprising an inner tube (20a) and an outer tube (20b), a monopole antenna (21) being attached to one end of said inner tube (20a), for directing the microwaves generated by said microwave generating apparatus (10) to the monopole antenna (21), a resonator (22) composed of dielectric material for holding the monopole antenna (21), and a chamber (23) in which a specific process gas is fed for plasma excitation. The chamber (23) has an open surface and the resonator (22) is placed on this open surface, and the process gas is excited by the microwaves radiated from the monopole antenna (21) through the resonator (22) into the interior of the chamber (23) to generate plasma.

An electromagnetic relay is provided which is small in size and is capable of controlling two circuits of an ordinarily-open contact, which has a large current-carrying capacity and high interrupting capability, and which is excellent in resistance against shock and vibration. Movable contactors are held, through bow-shaped movable contactor springs, to two -shaped holding frames each being electrically separated and being mechanically connected via a card made of a highly heat-resistant resin in a card block. Thick-plate shaped movable contacts, which are attached to the movable contactors in a fixed manner, are electrically connected or disconnected to fixed contacts in a base block, in synchronization with operations of an armature of an electro-magnet block. In order to improve a current-carrying capability and interrupting capability, there are provided two pieces of ordinarily-open contacts which are connected in series to each other, and between which an interval is doubled, in each of two circuits.

A heat treatment system for controlling the temperature in a processing vessel. The system includes a cylindrical processing vessel; a supporting table, raised by a support from the bottom portion of the processing vessel, for mounting thereon an object to be processed; and a processing object heating part provided in the supporting table, for heating the object to be processed. In addition a thermoelectric conversion element capable of selectively heating or cooling is provided in the bottom portion of the processing vessel, a resistive heater is provided in the side wall of the processing vessel, and a temperature control part for controlling the operations of the thermoelectric conversion element and the resistive heater is provided. Thus, it is not only possible to appropriately control the temperature in the processing vessel, but it is also possible to reduce space and energy, by combining the resistive heater with a thermoelectric conversion element.

A rotary electric machine comprising a stator and a rotor arranged opposedly of the stator. A magnet is provided on the stator or a frame for holding the stator at a position so as to be constantly opposed during rotation to a portion of the magnetic body of the rotor. The magnet is disposed at a position other than at a portion at which the magnetic action for rotation of the rotor occurs. The rotor is therefore constantly biased so that rotor play is minimized and non-repeatable deflections of the spindle are eliminated.

A rotary floater (30) for supporting an object to be processed (W) is floated by the magnetic attraction of a floating electromagnet assembly (F), and the rotary floater (30) is rotated by the magnetic attraction of a rotary electromagnet assembly (R) while its horizontal position being controlled by the magnetic attraction of a positioning electromagnet assembly (H). The floating electromagnet assembly (F) causes the magnetic attraction to act vertically upwardly, so that the rotary floater (30) is floated and suspended without contact with the inner wall of a processing container (2).

A surface wave plasma generating antenna serves to generate a surface wave plasma in a chamber by radiating into the chamber a microwave transmitted from a microwave output section through a coaxial waveguide including an outer conductor and an inner conductor. The surface wave plasma generating antenna is formed in a planar shape and has a plurality of slots arranged in a circumferential direction, and each joint portion between two adjacent slots in the circumferential direction is overlapped with at least one of the slots in a diametrical direction.
