OTF-1200X-RTP-II-5-R is an advanced rapid thermal processing (RTP) furnace, which is designed for CSS (Close Spaced Sublimation) film coating up to 12" wafer at the working temperature of 950°C Max. The furnace is heated by two groups of halogen heaters (Top and Bottom) separately with max. 20ºC/s heating rate. The top sample holder is rotatable to achieve a uniform coating. It is an excellent tool to research new generation thin films for solar cells, such as CdTe, Sulfide, and Perovskite solar cells, and also can be used for annealing 12" semiconductor wafers.

SPECIFICATIONS:

Furnace structure	The Vacuum chamber ( 20" ID) is made of Stainless steel to reach 10-5 torr via turbopump Two 12" IR heating plates are located on the top of the bottom inside the chamber The top sample holder is rotatable at a speed of 1 - 10 RPM for uniform film deposition Max. working temperature is 950ºC and The heating rate can reach 1200oC/minute max. Eurotherm precision temperature controller with +/- 0.1oC accuracy Touch Screen Computer control for all processing parameters
Power	208 - 240VAC, three phases, 50/60 Hz ( 380V AC 3 phase is available ) 60 KW max. ( 200A breaker needed ) A power cable is included, but no plug
Vacuum Chamber	Chamber dimension: ID 500mm x H 460mm Two 60mm dia quartz windows are built for easy observation. One air-tight sliding baffle is built-in for blocking the evaporation source under high vacuum/ A precision anti-corrosion digital vacuum gauge is in the standard package (Pic. 1) Vacuum level: 10-5 torr by turbopump ( Pic. 2) or 10-2 torr by a mechanical pump (pic. 3) Please click Pic.2 2 or 3 to choose the vacuum pump at extra cost Pic.1 Pic. 2 Pic. 3
Heater and Sample Holder	Two IR heaters are located on top and bottom of the chamber with adjustable gaps from 2 - 25 mm. (Pic. 1 Heaters are made of stainless steel with a water cold jacket to keep heat insulation. 12 " Dia. the circular wafer holder is built into the top heater for holding the substrate. The graphite plates are placed on the top of the IR heater to make heating more uniform (Pic. 2) The top sample holder is rotatable at an adjustable speed from 1 - 10 RPM A 58L/min circulating water chiller is included for cooling heaters (Pic.3) Pic. 1 Pic. 2Pic. 3
Control System	Two Eurotherm 3000 digital temperature controllers with 24 segments programmable offer independent controlling of top and bottom heaters with +/- 0.1ºC accuracy All operations, such as temperature profiles, vacuum pressure, rotation speed, rotation speed and lifting of the flange are controlled by a touch screen computer via a PLC. The computer can show the temperature and vacuum profiles and star 10 pre-set programs of processing
Working Temperature	Max. temperature for each heater: ≤ 950ºC. Max. the temperature difference between the two heaters: ≤ 300ºC Max. Heating: < 8ºC/s ( heating single heater only ) Max. Cooling: < 20 ºC/s (600 - 100ºC) Max.
Heating & Cooling Rate	Heating: < 8ºC/s ( heating single heater only ) Cooling: < 10ºC/s (600 - 100ºC) Max.
