Abstract
The initial oxidation of polycrystalline Si is investigated in order to determine differences in oxide growth at grains and grain boundaries. Auger electron spectroscopy is used to spatially resolve the surface oxidation that has been performed in situ in the UHV analysis chamber under controlled temperature and pressure conditions. Angular-resolved x-ray photoelectron spectroscopy provides information on the composition and thickness of the oxides. The transition layer between the SiO//2 and Si is estimated to be in the range of 4-15 A, depending upon the region in which it is measured. Comparison of these angular-resolved XPS data are made between single grain and grain boundary regions.
