The Solaris 150 is a manual loading “Rapid Therm Process” (RPT) or “Rapid Thermal Anneal” (RTA) system for R&D and pre-production. The Solaris 150 can process up to 152.4mm substrates at a temperature range from RT- 1200 degrees. The unique temperature measurement system of the Solaris requires virtually no calibration for different wafer types and backside emmissivity differences.

The Solaris uses a unique PID process controller that ensures accurate temperature stability and uniformity. The system can accommodate four interlocked MFCs for gas mixing and forming gas processing. The Solaris is designed for silicon implant annealing and monitoring and compound semiconductor implant activation and ohmic alloying.
