Using wavelength-dependent emissivity of semiconductor wafer to model heat transfer in rapid thermal processing station

摘要

This paper develops an approach for using a wavelength-dependent emissivity model of a semiconductor wafer in calculating heat transfer in a rapid thermal processing (RTP) station. The wafer emissivity is modeled by a generalized polynomial in wavelength where the coefficients may be functions of temperature. A comparison of experimental data with simulated results for a silicon wafer is provided.
