General Information and Usage:

Our rapid thermal annealer is manufactured by AET. Heating is achieved through two banks of heat lamps that deliver optical energy through the all-quartz chamber. With this unit, near atmospheric pressure anneals in Nitrogen, Forming Gas (10%H2 / 90%N2), or Dry Air (~ 10%O2 / ~ 90%N2) can be done to temperatures up to 1200°C for three minutes. An inner liner is used to prevent contamination to the main quartz chamber. A thermocouple and pyrometer are available for maintaining temperature control. The system can hold one 4-inch wafer or smaller substrates placed on top of a Silicon carrier wafer. Custom windows based control software has been added to the system by Sedona Visual Controls. All process parameters are monitored and stored. Typical anneals are done for: ohmic contact formation to semiconductors, implant activation, damage annealing, dopant activation, and film densification. A variety of materials can be annealed in the chamber, including Si, SiO2, Si3N4, GaAs, InP, GaSb, GaN, and metals. For materials that will decompose at the elevated temperatures, a dielectric anneal cap must be deposited on the wafer or an enclosed wafer holder must be used to prevent contamination of the chamber walls.

 

Detailed Specifications:
