PLASMA APPARATUS AND METHOD FOR PROCESSING A SUBSTRATE

摘要

Embodiments of the invention generally provide a method of forming a nitride gate dielectric layer. The method includes generating a nitrogen-containing plasma in a processing chamber via introduction of a nitrogen-containing processing gas into the processing chamber and the application of an ionizing energy to the processing gas, and pulsing the ionizing energy to maintain a mean temperature of electrons in the nitrogen-containing plasma of less than about 0.7 eV.
