S1. Advanced Lithography

Wednesday, February 5 | 1:00 pm - 5:10 pm

Remaining Issues of EUV

After more than 30 years of relentless effort to realize it, EUV finally got into the high volume manufacturing stage by leading companies of semiconductor industry. Advanced lithography session of the STS 2020 will provide the best opportunity to discuss and review the status and challenges of this long awaiting technologies under the theme of "Remaining issues of EUV". Prominent figures of the academia and industry will provide the most up-to-date information on the latest progresses of EUV lithography and its remaining challenges on various areas of EUV lithography. Topics will include exposure tools, optics, materials, mask, OPC and processes integration in view from the various sectors and stake holders of EUV lithography technology. The extendibility issues of EUV such as high NA EUV will be touched in the session as well.
