Direct measurement of the stress evolution is reported during reactive magnetron sputtering of WNx using a wafer curvature-based technique. It was found that the film stress changes significantly from compressive to tensile during crystallization. The nitrogen concentration in the films was determined by X-ray photoelectron spectroscopy.
