  • Patent number: 6319371
    Abstract: A film forming apparatus comprises a sputtering chamber, a cooling drum disposed at an central portion thereof for cooling a roll film in contact with the surface thereof, a roll chamber, an SiOx film forming chamber and a monitor room disposed to the periphery of the drum, a sputter cathode disposed to the SiOx film forming chamber, and a moisture pump such as a cryogenic panel disposed in the film forming chamber for effectively discharging the moisture by which the partial pressure of the moisture in the film forming chamber is kept roll, in which the light absorption of the SiOx film after formation is monitored by an InSitu transmission light monitor, the value x for the SiOx is judged by the transmittance of light of the SiOx film to control the oxygen flow rate by an MFC such that the value x reaches an aimed value, thereby enabling to form an adhesion layer having sufficient adhesion and good permeability on the substrate.
    Type: Grant

  • Patent number: 6228234
    Abstract: The invention provides an apparatus for sputtering, with which it is easy to control gas flow rate in a short time, and relates to an apparatus for sputtering in which reactive gas is supplied to a gas distributor having a plurality of gas nozzles provided in a vacuum chamber, the reactive gas is jetted from the gas nozzles, and a gauge port type connector for detaching the gas distributor is provided in the vacuum chamber. The gas nozzles comprise screws, each screw has a hole for jetting reactive gas and is directed in the outside direction of the chamber. Therefore, it is possible to change the gas flow rate easily in a short time.
