Proposal of Plane-Parallel Resonator Configuration for High-NA EUV Lithography

This project is a scientific proposal (arXiv:2201.06749) rather than a software tool, targeting the extreme niche of semiconductor lithography equipment. Its defensibility is low (3) because, despite being a novel technical approach to a hard problem (High-NA EUV), it lacks any industrial validation, patent backing within the repo, or community traction (0 stars). In the semiconductor industry, 'moats' are defined by multi-billion dollar CAPEX and proprietary manufacturing processes held by a monopoly (ASML). While the idea of a plane-parallel resonator configuration addresses known issues like the shadow effect and CRA in EUV, it competes with ASML's existing anamorphic lens designs for High-NA. Frontier AI labs (OpenAI/Google) have zero risk of building this, as they are consumers of the chips produced by such machines, not the OEMs. The platform domination risk is high because if the technology were viable, it would be absorbed or blocked by ASML or a major research institute like IMEC. The displacement horizon is long (3+ years) because the lithography equipment lifecycle is measured in decades. Without physical implementation or industry partnership, this remains an academic curiosity with high 'valley of death' risk.
