1200C Tube Furnace with Internal Travel Mechanism For HPCVD - OTF-1200X-S-HPCVD

MTI

OTF-1200X-S-HPCVD is a compact 2" split tube furnace with an internal sample traveling system inside the processing tube. This allows the position & temperature control of the sample stage or crucible via touch screen digital controller. It is designed for multi-functional rapid thermal processing, such as hybrid physical-chemical deposition(HPCVD), rapid thermal evaporation (RTE), and as well Horizontal Bridgman Crystal Growth ( HDC) under various atmospheres for new-generation crystal research.

SPECIFICATIONS:

Split Tube Furnace
  • 208 - 240 VAC, 50/60Hz, 1.2 KW max. power consumption
  • Working temperature: 1100°C continuous and 1200°C Max.
  • 2" quartz tube (50mm O.D x 44mm I.D x 450mm L)  with vacuum-sealed flanges.
  • Optional: you may choose a dual-zone tube furnace at Pic below right at extra cost to create a higher thermal gradient or longer constant temperature zone

Internal Traveling Mechanism &
PLC Control Panel
  • One 1/4" Dia. x 24'' long K-type thermal couple is inserted through the right flange to support a mini-crucible boat in the chamber. (click pic.1 to view)
  • A step motor ( 24VDC, 100W) drives the crucible inside the tube from the heating center to the right end of the furnace, L100 mm max. with air-tight
  • Touch screen panel allows control of travel distance and temperature display of crucible position (click pic.2 )
  • Traveling speed is constant at 180mm/ min. ( variable speed control is available upon request at additional cost )
  • A 50x20x20mm mini-crucible boat (~20ml) is installed on a thermal couple (click pic.3 to view).
  • AIN Sample Holder or Graphite Flat Substrate Holder for the wafer is available upon request, additional customization fee will apply (click pic.4 to view).

Max. Heating & Cooling Rate
The max heating and cooling rate can be achieved by moving the sample into the pre-heated hot zone and moving the sample out from the hot zone. The typical ramp/cool rate is listed in below:
  Heating Rate:
 10°C/sec (150°C - 250°C);
7°C/sec (250°C - 350°C);
4°C/sec (350°C - 500°C);
3°C/sec (500°C - 550°C);
2°C/sec (550°C - 650°C);
1°C/sec (650°C - 800°C);
0.5°C/sec (800°C - 1000°C);
Cooling Rate:
10°C/sec (950°C - 900°C);
7°C/sec (900°C - 850°C);
4°C/sec (850°C - 750°C);
2°C/sec (750°C - 600°C);
1.5°C/sec (600°C - 500°C);
1°C/sec (500°C - 400°C);
0.5°C/sec (400°C - 300°C);
 
Optional Parts

  • You may order a multi-channel gas delivery system for DVD or CVD operation ( Pic 4)
        
Laptop, software (Optional)
   
  • Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) for immediate use.
  • Labview-Based Temperature Control System (MTS01)enables users to edit temperature profiles, manage heat-treatment recipes, and record and plot data for MTI furnaces.


Compliance
  • CE Certified
  • NRTL or CSA certification is available upon request at extra cost.
Warning
  • Tube furnaces with quartz tubes 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

Application Notes This multi-functional furnace is suitable for the applications in below:
  • RTE: Crucible loaded with evaporation material is placed in the center of the furnace, and moves sample holder to a downstream position with the appropriate temperature where the deposition takes place.
