Specific Introduction:
    KJ-1200X-II-50 is a dual-zone PE-CVD tube furnace system which consists of 300W RF plasma source, speed controlled slidable mechanism, a pre-heater for sublimating the solid material and a high-quality oil-less vacuum pump. Such a PE-CVD furnace is a new tool to grow nanowire and for CVD coating of a wide range of material with the following benefits:

  • Lower temperature processing is required compared to the conventional CVD
  • High heating & cooling rate using a sliding furnace
  • Dual heating zone to create a thermal gradient up to 500ºC 
  • 1100ºC Max. the working temperature in the tube furnace
  • 1100ºC Max. the working temperature in pre-heater for heating vapor phase or evaporating solid materials
  • Rapid cooling & Heating for growing 2D  materials
Dual Zone Split Tube furnace 

  • Max 1100ºC for continuous heating
  • Two programmable precision digital temperature controllers with 30 segments.
  • Two separate controlled Heating Zones
    • 200mm length for each heating zone
    • 400mm total in heating length
    • 250mm constant central temperature heating area if both zones were heated at the same temperature
    • 500ºC max temperature difference between two zones with thermal blocks in between
  • Input power: 208 – 240V AC input, a single phase at max. 4KW

Plasma RF Power Supply

  • Output Power:           5 -300W adjustable with ± 1% stability.
  • RF frequency:           13.56 MHz ±0.005% stability.
  • Reflection Power:       200W max.
  • Matching:                  Automatic
  • RF Output Port:         50 Ω, N-type, female
  • Noise:                       <50 dB.
  • Cooling:                     Air cooling.
  • Power:                      208-240VAC, Single Phase, 50/60Hz
Pre-heating furnace
  • Small tube furnace with 200mm length single heating zone
  • Max. temperature:  1100ºC
  • 30 segment programmable temperature control
  • The vapor goes through the heater first before getting in the RF Plasma generator.
  • It can put solid material in the heater for evaporation and mixing with the vapor phase.
  • Quartz Tube:   50mm OD x 44mm ID x 2200 mm L   ( 80mm OD tube is available at extra cost)
  • Vacuum flange:  included 
Anti-corrosive Pressure Gauge
  • 3.8x10-5 to 1125 Torr measurement range
  • Anti-corrosive, gas-type independent 
  • High accuracy and reproducibility at atmosphere for reliable atmospheric pressure detection
  • Fast atmospheric detection eliminates waiting time and shortens process cycle
  • Easy to exchange plug & play sensor element
Oil-less Vacuum Pump Station and Valves
Pfeiffer's High Speed ( 226L/min) Oil-less Dry Vacuum Pump, 10E-3 Torr Limit is installed inside the heavy-duty mobile cart
KF25 adapter and stainless steel pipe are connected between the pump and tube flange with precision ball valve for customer's plug and play
10E-2 Torr vacuum can be achieved inside the processing tube
Sliding mechanism
  • Sliding rail and screw are built in the bottom furnace, which can move from one side to another as a program to achieve faster heating or cooling.
  • Sliding speed is adjustable from  0-70 mm/s

Heating & Cooling Rates
  • RS485 port and software are installed and allow remote control temperature profile by PC (not included, customer can order one from here)
  • In order to achieve Max.heating rate,  the user must preheat furnace to the desired temperature, then slide the furnace to the sample zone of the tube
  • In order to achieve the Max. cooling rate, push the heated furnace from hot zone to cold zone

  • Two - Four precision mass flow meters (0.02% accuracy) with digital displays are available as options, which can replace the bottom case to control the gas flow rate automatically with the system.
