Abstract
The present invention is a method for improving transistor channel hot carrier reliability by incorporating a solid deuterium source into the transistor structure. This is accomplished by using a deuterium containing source gas for formation of components of the transistor structure. A deuterium sinter, shown to improve channel hot carrier lifetime, is made a more viable process step by using deuterium as a source gas for formation of components made of silicon nitride. Additionally, time and/or temperature of the sinter may reduced. Incorporation of deuterium containing components which allow sufficient outdiffusion of deuterium may eliminate the need for a final deuterium sinter.
