The  Furnace  is a Vertical vacuum-sealed furnace.It equips an Ø200×Ø190×H425 mm quartz tube chamber with stainless steel flange and valves, which can achieve a vacuum of 10-5 via Torr turbopump. It is designed for calcining or annealing semiconductor wafers (up to 8") under vacuum or various other gas atmospheres with a temperature of up to 1100°C.

SPECIFICATIONS

Power

Voltage: Single-phase 208 - 240 VAC / 50/60Hz, (25 A breaker installed)

3 KW max. 

Note: Power cable included but without the plug. Please install a plug by your own 

Working Temperature

<1100°C under ambient pressure


<1000°C under vacuum

GE214 quartz tube is available for 1150oC working temperature at extra cost.

Heating Rate

<20°C/ min

Recommended: 10°C/ min

Heating ElementsNi-Cr-Al resistance wire
Quartz Tube & Effective Heating

Tube size: Ø200×Ø190×H425 mm


Max. loading 40Kg

Heating area Ø240×H245 mm

Vacuum Flange

Stainless steel vacuum flange with dual high-temperature silicone O-rings with water cooling jacket

One 1/4 gas inlet and one gas outlet with needle valves. 

One bored Al2O3 foam refractory block (190Dia x 50mm) is provided

K25 port is built-in for connecting to the vacuum pump

Mechanical Vacuum Gauge (included as standard accessory), which ranges from -0.1 to 0.15Mpa

Water CoolingA water-cooling jacket has been built inside the flange to protect the vacuum sealing assembly from melting at over 200°C.  16L/min water flow required.
Temperature Controller

NRTL certified digital temperature controller is included

Proportional–integral–derivative control (PID control) and auto-tune function

30 segments programmed with ramping, cooling, and dwelling steps

Built-in over-temperature alarm and thermocouple failure alarm

+/- 1 ºC temperature control accuracy

THE Default DB9 PC communication port included for connecting to PC

Eurotherm Temperature Controller is available at the extra cost with +/-0.1°C accuracy

Options

Digital Pressure Gauge (optional) A gas-type independent(above 10mbar) digital vacuum gauge with a wide range between 3.8 x 10-5 to 1125 Torr. 

You may choose a gas mixer to deliver multiple gasses with control over gas composition and flow rate

The furnace can be modified into a faster heating and cooling furnace

Vacuum Pressure

Vacuum Level is dependent on the vacuum pump used, connected pipe, interior refractory block's materials, etc. By using KFD25, stainless steel pipe, HT's two-stage mechanical pump, and KF25 Ball valve, the furnace can achieve vacuum levels below:

10-2 torr via mechanical pump within 30 minutes without thermal Block

10-5  torr via turbo-pump within 30 minutes with the Quartz Thermal Block at 900C


OptionsYou may choose a gas mixer to deliver multiple gasses with control over gas composition and flow rate 
Overall Dimensions500×530×880 mm
Net Weight70 kg
Shipping Weight45"(L) x 28"(W) x 35"(H)
Warranty

One-year limited warranty with lifetime support (consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below.).  

ATTENTION: Any damages caused by the use of corrosive and acidic gasses are not under the coverage of HT One Year Limited Warranty.

Compliance

CE Certified

NRTL or CSA certification is available upon request at extra cost.

Warning

Tube furnaces with quartz tubes are designed for use under vacuum and at low-pressure < 0.2 bars 

Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.

A maximum temperature of 1000°C should be imposed on all quartz tube furnaces to avoid the quartz tubes undergoing deformations under vacuum.

The flow rate for gasses should be limited to < 200 SCCM for reducing thermal shocks
