A computer-software, EMISSIVITY, has been developed to calculate the emissivity (ε) of silicon wafers of any surface morphology, for a given temperature and dopant concentration. The software uses a combination of ray- and wave-optics approaches to include the interference and the polarization effects necessary for multilayer surface coatings and multi-reflections within thin wafers. The refractive index and the absorption coefficient are calculated as a function of temperature and dopant concentration using an empirical model for an indirect bandgap semiconductor. The results of this model are compared with conventional emissivity calculations and experimental data.
