Abstract
A concise explanation of spectroscopic scatterometry is presented that is used for modelbased shape metrology of etched features in the production of Memory and Logic semiconductor devices. We also present an angle-resolved scatterometry technique that can measure at high throughput on very small test targets. First measured results are shown that demonstrate the capability on 5×5 μm2 targets.
