Paper Abstract

A simple and nondestructive low energy electron beam surface SEM is used in-line to measure the active width with LOCOS isolation. The method resulted in photos with excellent contrast between the silicon and oxide. Also a good correlation between the surface SEM data and electrical measurements is obtained in the submicron region where the active width reduction is a strong function of the LOCOS nitride width. The method can be used to significantly reduce the technology development time by accurately measuring the active width in-line.
