Abstract
An improved field effect transistor formed in the Group III nitride material system includes a two part structure in which a chemical vapor deposited passivation layer of silicon nitride encapsulates a previously sputtered-deposited layer of silicon nitride. The sputtered layer provides some of the benefits of passivation and the chemical vapor deposited layer provides an excellent environmental barrier.
