A critical dimension, or width, of a feature, or a semiconductor device, can be measured to provide direct and meaningful information regarding the impact of line end shortening, or length, on the function of the device. Specifically, a location on the feature where the width will have an impact on device performance can be selected. Using a simulation, the width at that location can be computed. Given the difficulties of direct measurement of line end shortening and the relationship between the width measurement and the impact on device performance, better layout checking is facilitated than by standard measurements of line end shortening.
