A New Process for Depositing Tungsten Nitride Thin Films

Abstract
A new process for depositing tungsten nitride (WNx) thin films is reported. It is based on plasma‐enhanced chemical vapor deposition (PECVD) using chemistry. High purity films that are stable in air have been obtained using the PECVD process. Effects of process conditions on conformality, film purity, and morphology are examined.
