  • Patent number: 8833388
    Abstract: According to one embodiment, there is provided pressure controlling apparatus including a detecting unit, an exhaust pipe, a regulating valve, and a pressure controlling unit. The regulating valve includes a valve port, a changing unit, and a slide valve. The valve port is communicated with the exhaust pipe. The changing unit changes a shape of the valve port to a different shape whose center is located near the central axis of the exhaust pipe. The slide valve regulates an opening degree of the valve port changed by the changing unit. The pressure controlling unit controls changing of a shape of the valve port by the changing unit and regulation of an opening degree of the valve port by the slide valve.

  • Patent number: 8760053
    Abstract: According to one embodiment, a power supply control device of a plasma processing device having a plasma generation unit which generates plasma in a process chamber. The power supply control device includes a radio frequency power supply, a storage unit, and a matching circuit. The radio frequency power supply supplies a power to the plasma generation unit. The storage unit stores matching information including a first matching value, a second process condition, and a third matching value. The first matching value corresponds to process information of a first process condition. The second matching value corresponds to process information of a second process condition. The third matching value corresponds to process information of a transient state where the first process condition is being switched to the second process condition. The matching circuit matches impedances based on the matching information.

  • Patent number: 8651135
    Abstract: According to one embodiment, a flow rate adjusting unit is disposed on a gas passageway and includes a valve that adjusts the flow rate of a gas and an actuator that controls the displacement amount of the valve. A displacement amount storage unit stores displacement amount information in which a displacement amount of the valve, used when a gas flows into the gas passageway at a flow rate defined according to a process procedure before performing the process procedure, is obtained in advance for each process procedure. A setting circuit acquires the displacement amount corresponding to the process procedure from the displacement amount storage unit, and controls the actuator on the basis of the acquired displacement amount.

  • Publication number: 20120000887
    Abstract: According to one embodiment, there is provided a plasma treatment apparatus including an electrode, a first power supply circuit, a plasma generating unit, a second power supply circuit, a sensing unit, and a control unit. The electrode is arranged inside a treatment chamber. On the electrode, a substrate to be treated is placed. The first power supply circuit supplies power to the electrode. The plasma generating unit generates plasma in a space separated from the electrode inside the treatment chamber. The second power supply circuit supplies power to the plasma generating unit. The sensing unit senses a parameter output from the first power supply circuit. The control unit controls power supplied from the second power supply circuit so that the parameter sensed by the sensing unit becomes close to or substantially equal to a target value.
