Abstract

Results are presented that demonstrate the use of laser ultrasonic methods to determine the temperature of silicon wafers under conditions consistent with applications in the RTP industry. The results show that it is possible to measure the temperature of Si(100) wafers to an accuracy approaching ± 1°C (1σ) even with wafer thickness variation over a range of 2 to 3 percent.
