Design Features

  • UHV multichamber magnetron sputter deposition system with combination of confocal and face to face sputtering.
  • The standard sample size and shape is 2″ wafer. Special shaped RHK STM samples possible too.
  • UHV deposition chamber with nine 2″ magnetrons, three 3″ magnetrons and one multipocket e-beam source installed.
    • Except of two 2″ magnetrons all sources can be used in face to face as well as confocal configuration.
    • All magnetrons with manual in situ tilting and easy change able magent system.
    • Linear multipocket e-beam with manual pocket exchange system and thickness controller incl. rate regulation & end point detection.
    • Fully motorized 3 axes sample manipulator with integrated motorized wedge shutter, RF bias potential and maximal sample temperature above 850°C.
    • Residual gas analyser system.
  • UHV sample preparation chamber with gridded DC ion source, DC plasma oxidation setup and magnet stage installed.
    • Fully motorized 2 axes sample manipulator with integrated DC bias potential and maximal sample temperature well above 900°C.
    • Manual translating plasma oxidation stage.
    • Magnet stage with motorized translation axis.
  • UHV surface analytik chamber with XPS, UPS, ion source, electron source, flood gun and ErLEED installed.
    • Fully manual 4 axes sample manipulator with integrated DC bias potential and maximal sample temperature above 900°C.
    • Manual translating UV source.
    • Manual translating X-Ray source with monochromator.
    • Manual translating X-Ray source without monochromator.
  • Storage chamber for 16 samples as part of the linear transfer system.
  • Load lock chamber with storage for 6 samples, installed lamp heating option and connection port to a mini glove box.
  • Semiautomatic sample transfer between all chambers via a linear distribution chamber system.
  • One STM chamber system provided by RHK is connected to the linear transfer chamber system.
  • Integrated bake out system with bake out tents at all chambers (except of load lock chamber).

Special Features

  • Titanium sublimation pumps (TSP) with cryo shroud installed at all chambers (except of load lock).
  • Handling incl. in situ exchange of sample masks in the sputter chamber.
  • Different sample sizes and shapes from 2″ wafer down to 10mm x 10mm samples can be handled (using different kind of sample holders).
  • Thin film deposition at STM tips possible in sputter chamber using special sample holder with included tip holder.
  • Parts of the system are placed in a second lab room (linear transfer moves through a hole in the wall between both rooms).
