ArF-resist-shrinkage and line-edge roughness-induced CD errors are the two main challenges for CD SEM. The requirement of measurement precision for the 65-nm node is less than 0.5 nm. The current CD SEM ADI precision is between 0.7 to 0.9 nm after sh

Metrology, Inspection, and Process Control for Microlithography XVIII.
For 90 nm technology and below, we need to fight for every nanometer to improve the CD uniformity (CDU). New materials, especially for low-k material, bring about not only complicated integration challenges, but also new metrology difficulties such a
