During rapid thermal processing, temperature non-uniformities are created due to patterned layers on the wafers. A theoretical calculation of this non-uniformity is presented. Results are in good agreement with previously reported experimental results. The influence of the RTP-system design, concerning lamp-system, window-type and chamber reflectivity is studied. Also, the influence of pattern size and steady-state temperature is discussed. For the technological important case of Si02 patterns on Si, specific examples are calculated. As a conclusion it is shown that when the patterns are on the front-side, heating of the wafer should be restricted to the back-side of the wafer, while the front-side of the wafer should face a highly-reflecting chamber.
