The effect of multiple reflections when analyzing the infrared spectra for oxygen measurements in silicon wafers is important. It may cause errors up to 20% when ignored. The procedure and calculations to derive oxygen concentration from the spectra by taking into account this effect is described in detail. The effect of back-surface finish on the measurements is also discussed.
