摘要
A concise explanation of spectroscopic scatterometry is presented that is used for model-based 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 5x5 mu m(2) targets.
