Abstract

Infrared transmission spectra of a series of silicon dioxide (SiO ₂) films grown on silicon wafers from a HCl and O₂ gas mixture at 850°C, have been studied for film thicknesses down to 28 Å. The validity of Lambert-Bouguer's Law for such thin films has been confirmed, and the apparent absorption coefficient calculated for the absorption at 1065 cm^-1 is in good agreement with previously published data for thicker, vapor-deposited, and thermally grown films. A continuous shift of the absorption near 1065 cm^-1 has been found, moving from an asymptotic limit maximum of ~1070 cm^-1 for thick films towards smaller wave numbers for thinner films. Various possibilities for the origin of this shift are discussed.
