0.0/5 rating (0 votes)

Description

OTF-1200X-III-HPCVD-S3 is a hybrid PVD and CVD  ( HPCVD) deposition system for preparing multilayer 2D materials. The system consists of a three-zone split tube furnace with the unique Source Feeding System that can drive the crucible into a processing tube at desired evaporating temperature. The three-zone split tube furnace can achieve fast heating up to 1200°C and create a different thermal gradient by setting different temperatures for each zone. The source feeding system can push and draw one or three crucibles with evaporation material through the atmosphere controlled 5" D tube furnace and sequentially process up to 3 crucibles (or co-evaporating of 3 at a time) as programmed. This is an ideal solution to conduct HPCVD experiments, especially for preparing multi-layer 2D crystal materials. Its built-in PLC touchscreen allows users to manage the feeding method and monitor the temperature of each source. Three programmable PID temperature controllers provide excellent control without temperature overshooting.  SPECIFICATIONS:

Furnace Structure	Features a unique Triple Channel source feeding system that drives  1 or 3 crucibles with evaporation material through the vacuum or atmosphere controlled tube, suitable for Hybrid Physical CVD-Growth of Multi-layer Film Stacks as programmed. Three independent temperature controllers to control each zone's temperature. Double-layer steel casing with air cooling keeps furnace surface temperature lower than 60°C.   High purity fibrous alumina insulation for maximum energy saving. The special refractory coating on liner and heating element helps increase furnace service life. Split cover with Interlock protection, cut the power if the door opens during the furnace heating process.
Power Requirement	Single Phase 208~240VAC, 50/60Hz, 10KW (70Amp circuit breaker is required)
Heating Zone Length	Three zones: each zone length is 11.8" (300 mm)
Temperature Range	100~1100°C (Continuous); 1200°C (<1 hour)
Max. Heating Rate	≤ 10°C /min
Temperature Controllers	Three digital controllers with 30 programmable segments for precise control of heating rate, cooling rate, and dwell time.  fr operation without attendant(s). +/- 1ºC temperature accuracy. Two K-type thermocouples (one for each zone). RS485 Communications Port. Optional:   The furnace can be operated by PC with an MTS02-Y Temperature control software package (include 2 communication chips and one 15" laptop).  Eurotherm 3000 controllers are available with +/- 0.1ºC accuracy at the extra cost.
Sequential Source Feeding System	Three thermocouples are connected to the three small quartz  tubes from the left flange. The stepper motor drives the tube to travel through the large tube together with the thermocouple for real-time temperature monitoring. Three crucibles can be simultaneously placed into the source feed system and delivered 1-3 crucibles into the hot zones for evaporation and deposition under a controlled atmosphere.  Each feeding channel has independent gas inlet and flow-control.

Compliance	CE Certified NRTLor CSA certification is available at extra cost.
Application Notes    Click here to learn the installation of a gas regulator.	Click here to learn How to set up a quartz/ ceramic tube and vacuum flange for MTI Tube Furnace. ( also, click the picture below to see demo video ) Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa.Vacuum pressure may only be safely used up to 1000°C. The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube. Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
