1200C Max. PECVD Split Tube Furnace (2" - 3.14" OD) w/ 4 Channels Gas Delivery & Vacuum Pump - OTF-1200X-PEC4LV

0.0/5 rating (0 votes)


OTF-1200X-PEC4LV is acompact PE-CVD (Plasma Enhanced Chemical Vapor Deposition) tube furnace system, which consists of 300W RF plasma source, 2"  or 3.14" O.D optional split tube furnace, 4 channels precision mass flow meter with gas mixing tank, and high-quality mechanical pump.   The PE-CVD furnace is an ideal and affordable tool to deposit thin films or grow nanowire from a gas state (vapor) to a solid-state, and benefits:
  • Lower temperature processing compared to conventional CVD. 
  • Film stress can be controlled by high/low frequency mixing techniques. 
  • Control over stoichiometry via process conditions.
  • Offers a wide range of material deposition, including SiOx, SiNx, SiOxNy and Amorphous silicon (a-Si:H) deposition.

Click here to learn the installation of a gas regulator
  • The tube furnaces with quartz tube are designed for use under vacuum and low pressure < 0.2 bars / 3 psi
  • 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.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
  • The flow rate for gasses should be limited to<200 SCCM for reducing thermal shocks to the tube
