Claim One:
1. A method of controlling a rapid thermal processing (RTP) reactor for processing a silicon wafer under a desired wafer time dependent temperature profile, the RTP reactor including at least one heating element and a partially transmitting component separating the heating element and the wafer, the method comprising the steps of: generating in a computer a spectral thermal radiation transport model of the RTP reactor for given heating element parameters; inputting into the computer data specifying the desired wafer time dependent temperature profile; selecting components for the RTP reactor based on the generated model; calculating an inverse of the generated model using the data specifying the desired wafer time dependent temperature profile to determine heating element parameters required to produce the desired wafer time dependent temperature profile, wherein the selecting step selects the components for the RTP reactor to meet control parameters indicated by the inverse of the generated model; and controlling the heating elements of the RTP reactor in accordance with the heating element parameters to heat the wafer in accordance with the desired wafer time dependent temperature profile.
