(11" O.D x 10.6" I.D x 51" L) |
| NOTE: The customers must define one tube size before purchase. It is very difficult to change the tube size after because the chamber liners need to be replaced in order to fit the different tube sizes. |
| Quartz boats (optional) | max. 4" wafer boat compatible
 | Max. 6" wafer boat compatible
 | Max. 8" wafer boat compatible
  |
| Furnace structure | - Double-layer steel casing with air cooling. The surface temperature of the case is < 70°C.
- Refractory fibrous alumina insulation liner for maximum energy saving.
- Heating element: NiCrAl Resistance Wire
- Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
- This furnace can be used as an annealing or diffusion furnace for 8" wafer uses a quartz boat at the related product below

| Heating zone | - Total heating zone length 900 mm (36")
- Three zones: 300 mm + 300 mm + 300mm (12" per zone)
- Constant temperature zone:
- 750 mm (if three zones are in the same temperature within +/- 3°C) longitude direction
- 600 mm (if three zones are in the same temperature within +/- 1°C) longitude direction
- +/- 3 oC along the cross-section

| Vacuum sealing & Flange
| A pair of SS vacuum sealing flange (Hinged Type) and 4 pieces of silicon O-ring are included. Left Side Flange: Vacuum gauge, stainless steel needle valves, and 1/4" barbed hose fitting. Right Side Flange: KF40 vacuum port with KF-40 Vacuum Right-Angle Valve for easy connection to KF40 bellows and pump. ( If using a pump with a KF25 port, you will need an adapter KF40-KF25. - One 1/4" OD thermal couple insert port is built in the flange for easy temperature calibration.
- Vacuum Level: 10-2 torr by heavy-duty mechanical pump and 10-4 torr by regular turbo-pump. 5x10-7 torr can be reached by 700 L/s high-speed turbopumps and a modified flange adaptor

Warning
 | - Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bar / 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 pressures may only be safely used up to 1000°C
- The flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
