Abstract:
1. A method of irradiating a substrate with a gas cluster ion beam (GCIB), comprising: providing a GCIB system comprising: loading a substrate to be irradiated with a GCIB; flowing a first gas mixture from the first gas supply through at least the first subset of nozzles and flowing a second gas mixture from the second gas supply through at least the second subset of nozzles to form the single gas cluster beam, wherein the first gas mixture and second gas mixture are different; directing the single gas cluster beam through the gas skimmer and then ionizing the single gas cluster beam to form a GCIB; accelerating the GCIB; and irradiating at least one region of the substrate with the GCIB to dope, grow, deposit, or modify a layer thereupon.
