Abstract
The invention is embodied in a novel method of forming titanium dioxide layers for metal-insulator-semiconductor device dielectrics. The titanium dioxide of a type known as rutile is formed by the deposition of titanium metal upon a layer of silicon dioxide and oxidation of titanium in an oxygen ambient at high temperatures.
