Abstract

This study describes a dynamic ultra-thin film thickness line-profile extraction capability from a warped Si substrate by adding a Mach-Zehnder interferometer scheme to a dynamic spectroscopic imaging ellipsometer system. The proposed system can provide nanometer-precision ultra-thin film thickness line-profile as well as the warped surface profile information of a Si substrate simultaneously and dynamically.
