STE RTA100 Rapid thermal annealing system System for rapid thermal annealing of semiconductor wafers in inert atmosphere STE RTA100 is intended for R&D activities and pilot production. Maximum diameter of wafers is 100 mm. Wafer is loaded into the chamber manually through upper quick access door and placed on heat-compensating graphite table. Heater system is based on linear halogen lamps and located under the table. This design ensures uniform wafer heating, having heterogeneous absorption of infrared emission along its surface (for example, wafer with formed metal topology). System allows carrying out relatively short-time processes with temperatures up to 1000°С and maximum heating rate up to 40°С/s. For applications not related with contact annealing, the system may be operated without graphite table, which is increased heating rate up to 200°С/s. Annealing time at maximum temperature is up to 10 minutes. The chamber is made of aluminum and has integrated water cooling 100 mm quartz window is provided for monitoring the wafer during annealing process and can be used also for installation of optional optical Pyrometer. STE RTA100 provides high run to run reproducibility and has long time and excellent references from the end users – manufacturers of electronic components based on III-V compounds. • thermal annealing in controlled gas environment with continuous purging of the chamber by inert gas • aluminum process chamber with water cooling
