Patent number: 8290553Abstract: A device for fabricating thin films on a substrate includes a vacuum chamber, a rotatable platen configured to hold one or more substrates within the vacuum chamber, and a housing disposed within the vacuum chamber. The housing contains a heating element and is configured to enclose an upper surface of the platen and a lower portion configured to partially enclose an underside surface of the platen which forms a reaction zone. A heated evaporation cell is operatively coupled to the lower portion of the housing and configured to deliver a pressurized metallic reactant to the reaction zone. The device includes a deposition zone disposed in the vacuum chamber and isolated from the reaction zone and is configured to deposit a deposition species to the exposed underside of the substrates when the substrates are not contained in the reaction zone.Type: GrantFiled: August 26, 2011Date of Patent: October 16, 2012Assignee: Superconductor Technologies, Inc.Inventors: Brian H. Moeckly, Ward S. Ruby
