Abstract

A numerical model has been developed to examine the temperature history of a multilayer wafer undergoing rapid thermal processing (RTP) for various doping densities. Partial transparency and thin film interference effects are considered. Doping levels from approx. 1015 to approx. 1018 cm-3 are examined. Numerical temperature predictions of the lightly doped wafer are compared with experimental measurements. Heating rates for the lightly doped wafer fluctuate due to partial transparency effects and reach a maximum of approx. 50°C/s. The heavily doped wafer sees a maximum heating rate of approx. 100°C/s. Because the wafers are opaque above 700°C regardless of their level of doping, all wafers reach steady state at approx. 845°C.
