Patent number: 10785859Abstract: A method for generating extreme ultraviolet (EUV) radiation employs an EUV apparatus, which comprises one or more sets of nanoscale antennas, designed for electromagnetic field enhancement. The one or more sets comprise, each, at least one pair of opposite antennas separated by a feedgap volume. First cations of same molecular entities are allowed to reach the feedgap volumes and the antennas are energized so as to perform one or more EUV radiation emission cycles, during which the first cations are further ionized via electromagnetic field intensities achieved in the feedgap volumes by optically exciting corresponding pairs of opposite antennas. Second cations are thus obtained, which have a higher charge state than the first cations, and are forced to radiatively decay, by electrically stimulating antenna pairs, whereby EUV radiation is generated and third cations are obtained, which have a lower charge state than the second cations.Type: GrantFiled: December 19, 2018Date of Patent: September 22, 2020Assignee: International Business Machines CorporationInventors: Emanuel Loertscher, Andrea Giovannini
