Abstract

Variable angle spectroscopic ellipsometry was used to characterize polysilicon multilayer structures. Five different multilayer wafers, each containing a polysilicon layer, were studied. Layer thicknesses and compositions were determined at several locations across each wafer. The thickness measurements obtained by ellipsometry are compared with those determined from cross-sectional transmission electron microscopy (XTEM).
