Qalitative and Quantitative Analysis of IC Designs

Non-volatile metal-insulator-semiconductor memory elements are fabricated using a novel sequence of steps for forming multiple dielectric layers including particularly a layer of titanium dioxide covering a layer of silicon dioxide covering a layer of silicon nitride. The titanium dioxide of a type known as rutile is formed by evaporation of titanium upon the silicon dioxide and oxidization of the titanium in an oxygen ambient at high temperatures.
