Abstract
Examples described herein generally relate to apparatus and methods for rapid thermal processing (RTP) of a substrate. The present disclosure discloses pulsed radiation sources used to measure a broad range of low to high temperatures in the RTP chamber, each at a discrete wavelength, are used at a low temperature regime before using one laser at a discrete wavelength for higher temperatures. In another example, a single laser is used for both the low temperature regime and higher temperatures. These methods are useful for detection of a broad range of low to high temperatures in the RTP chamber with varying substrate types.
