Abstract
The analysis proposed attempts to identify the systematic and non-systematic errors in linewidth uniformity data and their magnitudes. Specific to step-and-scan systems are various error components to linewidth such as optical slot errors, stage scan errors and wafer residual errors. We explore ways of handling these errors and applying developed methods to actual micrascan data in order to understand how to improve linewidth control.
