NST Compact 4″ RTP Tube Furnace System with Turbomolecular Vacuum Station & Complete Acessories (up to 1E-4 torr & 1100C )

 TMAX-1200X-RTP-4-HVis a UL certifiable compact rapid thermal processing tube (4″ I.D.) furnace with High Vacuum Station (diaphragm pump + turbo molecular pump) and KF-D25 vacuum flange assembly. It is designed for annealing semiconductor wafer or solar cell up to 3″ diameter. The furnace is heated by 8 units of 1KW halogen light around the processing tube with a max. heating rate of max. 50C/second. 50 segments precision temperature controller is built in with accuracy +/-1° C.

Furnace structure Compact 4“ RTP Tube Furnace(Double layer steel case mullite liner)
Heating element 8 pcs Halogen light tube (D=10 L=300 T =200, mm)
Working Temp. 1100° C max. (This RTP furnace’s max holding time shall be less than 600 seconds at 1000ºC ~ 1100ºC, otherwise O-ring may get melting )
Max heating rate 50°  C/sec
Max cooling rate 64° C/min (Under vacuum: 200 mtorr), 117° C/min (Under atmosphere pressure)
Heating zone 12″ length with 4″ constant temperature zone within +/-1°C uniformity
Program Temp. Controller
  • PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired, current limiting resistor.
  • 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
  • Please click here to learn why SCR is more accurate than SSC (Solid state relay).
  • Built in PID Auto-Tune function with overheating & broken thermocouple broken protection.
  • Over temperature protection and alarm allows for operation without attendant(s).
  • +/- 1 ºC temperature accuracy.
  • RS485 Communications Port.
  • PC Control:
    • A MTS-02 control module is included for PC control on this furnace.
    • The new version of PC module is now compatible with Lab View 05/08/2014
    • A laptop PC can be ordered for $900 together with the furnace. We recommend ordering a computer (laptop) from us to avoid software installation problems as we will perform installation and testing before shipping.


Quartz Tube & Sample Holder
  • Quartz Tube Size: 4.33″ O.D x 4.05″ I.D x 16.2″ Length
  • 3″ diameter Sample holder is inserted to sliding flange, which is made of quartz
  • One 3″ diameter AlN wafer is placed in the center of holder for annealing sample up to 3″ dia.
  • AlN has very high thermal conductivity, which provides the best temperature uniformity in the sample area
  • The sample holder is removable from flange
Vacuum flange KF-D25 High Vacuum Flange is made of stainless steel with double hi-temp. silicone O-rings, needle valves.
Sliding flange make an easy way for sample loading. 3″ Quartz sample holder.Insert-able thermal-couple for accurate measurement.
Water Cooling Jacket
  • Cooling water is required.
  • Please make sure the flow rate of cooling water is ≥ 10L/min, water temp. < 25ºC; pressure > 25 PSI.
  • We suggest using the EQ-KJ5000 Series recirculating water chiller as a cooling system (please order separately at related products below) to save water.

Warning: This RTP furnace’s max dwelling time shall be less than 600 seconds at 1000ºC ~ 1100ºC with tap water, otherwise O-ring may melt. With use of a recirculating water chiller, this holding time can be extended to 1200 seconds.

Flow meter One flow meter is installed on the front panel to adjust gas flow from 0 – 160 ml/min
Power input 208-240 AC, 50/60 Hz single phase, 9 KW Max. (> 60A breaker required)
HV Station
High Vacuum Station
  • Mobile cart size:  600 (L) x 600 (W) x 700(W), mm
  • Max. Loading:       600 Lbs on top
  • Molecular pump control Panel :   LCD digital
  • Diaphragm Pump and  Turbo Molecular Pump are installed inside the steel case.
Vacuum Degree 6.3E-5 mbar (with 4″ RTP tube furnace in 40 minutes)
Control panel
  • One button operation – the diaphram pump and the turbo molecular pump will start after pressing “start” button.
  • System controlled spining speed – the controller will control the speed of the turbine spining up and down according to the vacuum level and leaking rate of the reaction chamber.
  • Self protection – the system will protect the pump from damage by overheating and overcurrect if the leaking rate of the reaction chamber is too high to achieve high vacuum.
  • LCD screen – double lines parameters checking interface make the working easier to be handled.
