Abstract

This paper briefly reviews the use of a verified model to investigate light scatter metrology to detect the presence of defects in semiconductor circuit vias. Three types of defects are examined. Although defects can be detected, there are practical problems associated with separating defects from acceptable changes in dielectric film thickness.
