Announcement of the 6th EUV-FEL Workshop
Utilizing IoT, AI and related technologies, information processing devices and systems are evolving towards an ultra-smart society. To this end, EUV exposure technology using a laser plasma (LPP) light source has been introduced in the leading-edge semiconductor chip production.
At SPIE conference on Photomask Technology + EUV Lithography Digital Forum, which was held at the end of Sept. 2021, many topics were discussed for present and future EUV lithography technologies such as High NA EUV lithography exposure system. And the road map for fine patterning less than 3nm Node was clearly proposed. To achieve such aggressive targets, the EUV light source power should be increased to keep the performance. The further development of the LPP light sources in ASML and Gigaphoton, and the proof of concept of EUV-FEL for much higher EUV-light source in KEK (https://semiengineering.com/manufacturing-bits-oct-5/) were presented in this conference.
The workshop is planned to be held at the afternoon on 18 January, 2022 as an international online web-meeting using English as an official language. Tetsuro Higashi (Chairman Emeritus of TEL, Former Chairman and Directors Emeritus of SEMI, Chairman, Executive Board of TIA) and Atsuyoshi Koike (President of Western Digital Japan) will give key note lectures about the present and future semi-conductor industries in an international perspective. The invited speakers are; Zhilong Pan (Tsinghua University) and Norio Nakamura (KEK) for accelerator based high power light source, Hakaru Mizoguchi (Gigaphoton) for LPP light source, and Tsutomu Shoki (HOYA) for the latest development of EUV photomasks, respectively.
We hope that many people will discuss on EUV ultra-high-power light sources for the future at the meeting.
