0.0/5 rating (0 votes)


OTF-1200X-II-PEC4SL is a multi-zone slidable PE-CVD tube furnace system consists of 300W RF plasma source, with optional tube size and an integrated slidable rail, 4 channel precision mass flow meter with gas mixing tank, and a high-quality oil-less vacuum pump.  Such a PE-CVD furnace is a new tool to grow nanowire or graphene with the following benefits:

  • Lower temperature processing compared to conventional CVD
  • High heating & cooling rate using a sliding furnace
  • Each heating zone to create a thermal gradient up to 200ºC
  • 1100ºC Max. working temperature
  • Offers a wide range of material deposition, such as Carbon & ZnO nanowire (or tube) and single-layer graphene

  • Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.12 MPa (absolute pressure).
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  • The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube
  • Click here to learn How to set up a quartz/ ceramic tube and vacuum flange for MTI Tube furnace. Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
  • MTI reserves the right to modify its PE-CVD design at any time without notice but promises quality in future designs meet and exceed the specifications above.
  • For operating the PECVD system with tube size larger than 4", please always keep more than 1-meter distance from the plasma source after the plasma generator starts working
