  • Patent number: 9567667
    Abstract: System and method of insulating film deposition. A sputter deposition chamber comprises a pair of targets made of the same insulating material. Each target is applied with a high frequency power signal concurrently. A phase adjusting unit is used to adjust the phase difference between the high frequency power signals supplied to the pair of targets to a predetermined value, thereby improving the in-plane thickness distribution of a resultant film. The predetermined value is target material specific.

  • Patent number: 9551060
    Abstract: A film forming apparatus, for forming a metal oxide film on an object, includes a holding unit and a heating unit. The holding unit includes a first heater and holds the object in a processing chamber. A first heater power supply supplies power to the first heater. A target electrode is electrically connected to a metal target provided above the holding unit. A sputtering power supply is electrically connected to the target electrode. An introduction mechanism supplies an oxygen gas toward the holding unit. The heating unit includes a second heater for heating the object and a moving mechanism for moving the second heater between a region in a first space disposed above the holding unit and a region in a second space separated from the first space. A second heater power supply supplies power to the second heater.

  • Publication number: 20160071707
    Abstract: A processing apparatus includes a processing chamber, a rotatable mounting table, a cooling mechanism and a driving mechanism. A sputtering target is provided in the processing chamber. The rotatable mounting table is provided in the processing chamber and configured to mount thereon an object to be processed. The cooling mechanism is configured to cool the mounting table. The driving mechanism is configured to change a relative position of the mounting table with respect to the cooling mechanism. The driving mechanism changes a conductivity of heat from the mounting table to the cooling mechanism at least by switching a first state in which the mounting table and the cooling mechanism are separated from each other and a second state in which the mounting table and the cooling mechanism become close to each other.
