Investigation of the transition region between layers wet grown at and Si

Abstract
Silicon oxide layers wet grown at on silicon substrates of integrated circuit quality have been investigated by slow-positron-implantation spectroscopy and Auger electron spectroscopy. The total thickness of pure on top of a transition zone is determined by ellipsometric measurements; the positron/Auger results indicate that the transition zone extends over 15 - 23 nm. Its thickness decreases as the layer is thinned by a wet-chemical process at room temperature. The results are consistent with earlier secondary-neutral mass spectroscopy measurements.
