摘要:
Plasma processing of plural substrates is performed in a plasma processing apparatus, which is provided with a plasma processing chamber having an antenna electrode and a lower electrode for placing and retaining the plural substrates in turn within the plasma processing chamber, a gas feeder for feeding processing gas into the processing chamber, a vacuum pump for discharging gas from the processing chamber via a vacuum valve, and a solenoid coil for forming a magnetic field within the processing chamber. At least one of the plural substrates is placed on the lower electrode, and the processing gas is fed into the processing chamber. RF power is fed to the antenna electrode via a matching network to produce a plasma within the processing chamber in which a magnetic field has been formed by the solenoid coil. This placing of at least one substrate and this feeding of the processing gas are then repeated until the plasma processing of all of the plural substrates is completed. An end of seasoning is determined when a parameter including an internal pressure of the processing chamber has become stable to a steady value with plasma processing time.

摘要:
In a plasma processing method for conducting etching on an object to be processed by generating plasma from depositional gas introduced into a processing chamber and exposing the object to be processed to the plasma in a state in which radio frequency power is applied, the object to be processed is etched under etching conditions that a deposit film on an inner wall of the processing chamber becomes amorphous by repeating a first period during which the object to be processed is exposed to plasma and a second period during which the object to be processed is exposed to plasma and an etching rate is lower as compared with the first period. Consequently, particles due to increase in the number of processed sheets of the object to be processed can be suppressed.

Provided is an inexpensive seed material for liquid phase epitaxial growth of silicon carbide. A seed material 12 for liquid phase epitaxial growth of a monocrystalline silicon carbide includes a surface layer containing a polycrystalline silicon carbide with a 3C crystal polymorph. Upon X-ray diffraction of the surface layer thereof, a first-order diffraction peak corresponding to a (111) crystal plane is observed as a diffraction peak corresponding to the polycrystalline silicon carbide with a 3C crystal polymorph but no other first-order diffraction peak having a diffraction intensity of 10% or more of the diffraction intensity of the first-order diffraction peak corresponding to the (111) crystal plane is observed.

A micro movable device includes a movable member, a stationary portion, and connecting portions each connected to the movable member and the stationary portion. The movable member includes a pair of electrodes. The stationary portion includes a pair of electrodes cooperating with the electrodes of the movable member to generate a driving force for translating the movable member in its thickness direction. The connection points at which the respective connecting portions are connected to the movable member are spaced from each other. The electrodes of the movable member are positioned between two mutually spaced connection points, as viewed along the spacing direction of the two connection points.

An objective of the present invention is to secure the continuity of the communication between a client device and a standby server device, when a failure occurs and switch to the standby device is performed. A communication processing unit of the client device establishes connection with a plurality of server devices simultaneously by transmitting a UDP packet to the plurality of server devices by multicast. After establishing the connection, data of the application is transmitted by multicast to the plurality of the server devices. In the even of a failure, a standby server device receives the data packet multicast from the client device to continue the inter-application communication.
