Abstract
A process of passivating a metal-gated CMOS structure in which a metal-gated CMOS structure is passivated in an atmosphere of molecular hydrogen at a temperature of between about 250° C. and about 500° C. and a pressure of at least about 200 Torr. The present process provides a lower interface state density than obtainable by prior art passivation processes.
