OTF-1200X-RTP-4 is a compact rapid thermal processing tube furnace with a 4" I.D. processing quartz tube and vacuum flanges. It is designed for annealing semiconductor wafers or solar cells with diameters up to 3". OTF-1200X-4-RTP is heated by 8 units of 1KW halogen light with a max. the heating rate of 50ºC/second. 30 segment precision temperature controller with +/-1ºC accuracy is built into the furnace to allow for heating, dwelling, and cooling at various steps. RS485 port and control software are included to make monitoring the temperature profile via PC while simultaneously running furnace possible. This furnace also can be modified into an RTE, CSS or HPCVD furnace ( see below application note )

Quartz Tube & Sample Holder
|
|
|
Vacuum Flange
|
- KF-D25 High Vacuum Flange is made of stainless steel with double hi-temp. silicone O-rings, needle valves, and a water-cooling jacket.
- It only requires water cooling in long-running times at temperatures > 600oC.
- Circulating water rate: 0.5 m3 /hr.
- The slide-out flange provides an easier way of loading, unloading the samples and other specific processes needed.
- Insert-able thermal-couple for accurate measurement.
|
|
Vacuum Pump (optional)
|
- EQ-FYP vacuum pump is recommended for this furnace. The ultimate vacuum pressure in this system can be 10^-3 torr. Vacuum bellows and clamps are included in this package. Click here for the spec of EQ-FYP vacuum pump.
- Click here to view other models of pump and package.
|
|
Water Cooling (optional)
|
- 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.
|
|
Flow-meter
|
One flow meter is installed on the front panel for adjusting gas flow from 16 - 160 ml/min
|
|
Vacuum Gauge
|
A digital vacuum gauge with a measurement range from 10-4 to 1000 Torr is installed on the furnace.
|
|
Vacuum Pressure & Gas Fitting
|
- Pressure can reach 50 more by using a mechanical vacuum pump with KF25 adapter
- Pressure can reach 10-4 torr by the molecular pump with KF25 adapter
|
|

Application Notes
|
- Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°CThe flow rate for gasses should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
- 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.
- This furnace also can be modified into an RTE, CSS or HPCVD furnace with a graphite crucible coated with SiC ( click Pic-left for detail how to set up an RTE processing by DIY )
- After CVD, the graphene must be transferred from the metal catalyst to another substrate for most applications. By using the graphene transfer tape, the residue can below.
