Abstract
A wafer temperature control system is developed for Spike RTA. The nonlinear model of a halogen lamp developed in this paper does not require the filament temperature for identification. A nonlinear feedforward controller based on this model is applied to the latest rapid thermal processor, by which good tracking performance to set points and repeatability of top temperature are verified.
