Abstract
In this paper, we have evaluated the characteristics of T-topped patterns with LER, the width of the white band, and a correlation coefficient between the left and right borders of the white band. It can be concluded that the evaluation of these features enables us to recognize a T-topped profile of a resist-pattern edge from only one top-down image by CD-SEM.
