A substrate treatment apparatus is disclosed. The substrate treatment apparatus has an electrostatic chuck mechanism, a grounding mechanism, and an electron beam radiating mechanism. The electrostatic chuck mechanism electrostatically sucks and holds a substrate under treatment. The grounding mechanism freely contacts a predetermined film of a plurality of films formed on a treatment surface of the substrate under treatment sucked and held by the electrostatic chuck mechanism. The electron beam radiating mechanism radiates a resist film formed on the treatment surface side of the substrate under treatment with an electron beam.

A substrate treatment apparatus that treats a substrate under treatment has an interface section, a substrate loading/unloading section, a reduced pressure atmosphere conveyance chamber, and an exposure treatment chamber. The interface section has a conveyance mechanism that can freely load and unload the substrate under treatment from another device into the apparatus or vice versa. The substrate under treatment can be loaded and unloaded into and from the substrate loading/unloading section in one direction by the conveyance mechanism of the interface section. The reduced pressure atmosphere conveyance chamber is disposed adjacent to and perpendicular to the direction of the substrate loading/unloading section and has a conveyance mechanism that conveys the substrate under treatment under a reduced pressure atmosphere. The exposure treatment chamber is disposed adjacent to and in parallel with the direction of the reduced pressure atmosphere conveyance chamber and performs an exposure treatment for the substrate under treatment.

The present invention provides a discharge-pumped excimer laser device which includes a laser chamber filled with a laser gas that is deteriorated to a small extent, magnetic bearings and a motor that are resistant to the entry of dust particles, and parts that are held in contact with the laser gas and suffer little damage, and has a long service life. The discharge-pumped excimer laser device according to the present invention has a laser chamber (1) filled with a laserigas and housing at least a pair of main discharge electrodes (2, 2) for producing an electric discharge to be able to oscillate a laser beam, housings (6, 7) joined to opposite sides of the laser chamber (1), a cross flow fan (3) having opposite ends rotatably supported by magnetic bearings (8, 9, 10, 11) accommodated in the housings (6, 7), for producing a high-speed laser gas flow between the main discharge electrodes (2, 2), a motor (12) accommodated in the housing (7) for rotating the cross flow fan (3), laser gas flow passages (61, 62) extending through gaps between rotor side and stator side of the magnetic bearings (8, 9, 10, 11) and the motor (12) over an axial entire length of the housings (6, 7), and communicating with an interior of the laser chamber (1), a laser gas introduction passage (60) extending from the interior of the laser chamber (1) and communicating with the laser gas flow passages (61, 62), and filters (20, 20) disposed in the laser gas introduction passage (60).
摘要:
A substrate processing apparatus includes a substrate processing chamber; a mechanism for long and unloading a substrate into and out of the chamber; a substrate heating source provided in the chamber; and a raw material supply source for supplying a raw material toward the substrate for processing. During processing of the substrate, the raw material for processing is supplied from a surface facing a surface of the substrate to be processed. When the substrate and a holder on which the substrate is placed are moved to a predetermined position for processing in the substrate processing chamber, a space in the substrate processing chamber is divided by the substrate into an upper space serving as a reaction space for processing and a lower space where the substrate heating source, etc. are placed. The apparatus also includes a magnetic force source for holding the holder at the predetermined position in a levitational manner by a magnetic force during processing of the substrate.
摘要:
A rotor is placed in a space communicating with a processing chamber. Stator-side constituent members of magnetic bearings and a stator-side constituent member of a motor are placed in a space defined outside the space communicating with the processing chamber by a partition provided between the rotor and the stator-side constituent members. Further, a material electromagnetically equivalent to yokes of electromagnets as stator-side constituent members of the magnetic bearings is fitted in portions of the partition where the yokes are located. The partition constitutes a stator housing as a whole. The magnetic bearings include an axial magnetic bearing and a radial magnetic bearing. The axial magnetic bearing is divided into three or more magnetic bearings, which are positioned so that imaginary lines connecting points where the divided axial magnetic bearings are disposed form an approximately regular triangle or polygon.

A thin-film vapor deposition apparatus has a reaction chamber for holding therein a substrate in an atmosphere isolated from an ambient atmosphere. For depositing a thin film on the substrate, the temperature of an inner wall of the reaction chamber is adjusted to control the temperature of the atmosphere in the reaction chamber, and the temperature of the substrate is also adjusted independently of the temperature of the atmosphere in the reaction chamber, while the substrate is being rotated at a high speed in the reaction chamber. Reactant gases required to deposit a thin film on the substrate are ejected from a reactant gas elector head toward the substrate in the reaction chamber. Remaining and excessive gases are discharged out of the reaction chamber.
摘要:
A reactant gas ejector head enables a process gas mixture of a uniform concentration and composition to be delivered to the surface of a substrate in a stable and uniform thermodynamic state by preventing premature reactions to occur along the gas delivery route. The reactant gas ejector head comprises an ejection head body having a back plate and a nozzle plate for defining a gas mixing space therebetween. The nozzle plate has numerous gas ejection nozzles. A gas supply pipe is communicated with the ejection head body through a center region of the back plate so as to separately introduce at least two types of gaseous substances into the mixing space. Gas distribution passages are formed between the back plate and the nozzle plate in such a way as to guide the at least two types of gaseous substances from the gas supply pipe to be directed separately towards peripheral regions of the gas mixing space.
摘要:
A vapor feed supply system including a vaporizer device and a method of cleaning a vapor flow region employing such a vaporizer device enables thorough cleaning of the system, without having to degrade the overall system vacuum in the process of cleaning the vaporizer device. The method includes defining a cleaning fluid passage having a predetermined withstand pressure by isolating a cleaning region of the vapor flow region, and flowing a cleaning fluid into the cleaning fluid passage under a pressure so as to enable the cleaning fluid to remain in a liquid state at a cleaning temperature of the cleaning region.
