Abstract:
A method of manufacturing a heating furnace for use of wafer heating which has a light source and a lamp house surrounding the light source, the method comprising: a calculating process for determining heating distributions on a wafer where a light flux emitted from the light source is mirror reflected by a wall surface of the lamp house while the light flux is mirror reflected also by a surface of the wafer, tracing a path of the light flux attributable to the reflection on the wall surface of the lamp house as well as the reflection on the surface of the wafer, performing a calculation of converting an absorption of the light flux into thermal energy occurring together with the reflection at least on the surface of the wafer with respect to a plurality of light fluxes emitted from the light source and a structure determining process of the light source and the lamp house based on a result of the calculation.
