Abstract
High-NA EUV lithography will improve resolution by increasing the EUV scanner NA from 0.33 to 0.55. To fully benefit from the resolution gain offered by the better scanner lens, it is key to develop and improve the EUV ecosystem. The role of the ecosystem is to ensure timely availability of the advanced resist materials, photomasks, metrology techniques, OPC/imaging strategies, and patterning techniques. In this context, in parallel to the EXE:5000 0.55 NA EUV scanner manufacturing, imec and ASML, together with our partners, are addressing the main challenges and needs towards High-NA ecosystem readiness. In this paper, we will discuss the key findings from simulations and experimental work to develop the high-NA lithography ecosystem (resist and patterning, mask technology) and highlight the key areas where development is needed.
