AS-One Rapid Thermal Processing furnaces for the development of rapid thermal annealing and CVD processes

Versatile Rapid Thermal Processing cold wall chamber furnaces. 4-inch (100 mm) and 6-inch (150 mm) versions.



Versatile RTP system

The AS-One is a versatile RTP system that can be used for the development of rapid thermal annealing and rapid thermal CVD processes.

  • Rapid thermal annealing (RTA)
  • Implant annealing
  • Ohmic contact annealing (III-V and SiC)
  • Rapid Thermal Oxidation (RTO)
  • Rapid Thermal Nitridation (RTN)
  • Selenization (CIGS solar cells)
  • CVD of graphene and h-BN (hexagonal boron nitride)
  • Thermal annealing of polymers
  • Etc.


The AS-One RTP system is available for processing up 100 mm or up to 150 mm diameter substrates.

The Annealsys AS-One system is available with two sizes of reactors to process substrates up to 100 mm (4”) or 150 mm (6”) diameter. The machine has been specially developed to meet the requirements of research laboratories and small-scale production. The high reliability guarantees low cost of ownership. The floor standing configuration and the reduced footprint allow easy installation in cleanroom and easy access for maintenance.

The AS-One system has a stainless steel cold wall process chamber for better process reproducibility and higher cooling rates. The special design of the process chamber provides a low volume for fast pumping and purging and low consumption of process gases.

Pyrometer and thermocouple temperature measurements are standard features. The fast digital PID controller provides accurate and repeatable thermal control across the temperature range.

The clam shell style design of the process chamber enables full access to the bedplate and easy access for loading and unloading the substrates as well as a practical cleaning of the chamber.



The AS-One 100 allows performing annealing processes up to 1450°C

The high temperature version of the AS-One 100 allows performing annealing processes up to 1450°C. It is up to 1300°C for the AS-One 150.

  • Temperature range: RT to 1450°C (depending upon version)
  • Ramp rate up to 200°C/s (depending upon version)
  • Cooling rate up to 100°C/s with special equipment
  • Gas mixing capability with mass flow controllers
  • Vacuum range: Atmosphere to 10-6 Torr
  • Full PC control with Windows compatible software


The optional fast cooling system is available to increase the cooling rate by 4 times.

  • Graphite and silicon carbide coated susceptors
  • Rough vacuum pump and turbo pump, automatic pressure control with throttle valve
  • Fast cooling system
  • Selenization kits
