Abstract

System and method of gas-cluster ion beam processing is realized by incorporating improved beam and workpiece neutralizing components. Larger GCIB current transport is enabled by low energy electron neutralization of space charge of the GCIB. The larger currents transport greater quantities of gas in the GCIB. A vented faraday cup beam measurement system maintains beam dosimetry accuracy despite the high gas transport load.
