摘要
Wafer curvature measurements are a simple yet sensitive way to measure stress in thin films. A inultibeam optical system designed for in situ monitoring makes it possible to monitor the evolution of thin film stress in real time in a variety of deposition and processing environments. Examples of stress measurements in epitaxial systems, polycrystalline films and hard coatings are discussed.
