Beyond EUV: Blue-X explores sub-13.5nm lithography - Bits&Chips

As the semiconductor industry continues to advance toward smaller chip nodes, lithography technology faces unprecedented challenges. Recently, the international consortium Blue-X has begun exploring a... Read original →

Blue-X’s pursuit of sub-13.5nm lithography signals a strategic pivot from incremental NA scaling to wavelength innovation. This shift will force a full-stack redesign—from light sources and masks to resists and metrology—potentially disrupting ASML and Zeiss’s entrenched EUV ecosystem. Japanese and Korean material suppliers could seize this inflection point to penetrate core optical components. Geopolitically, Huawei’s 1.4nm-equivalent process—achieved without advanced lithography—already reflects the strain of U.S. export controls; Blue-X’s progress may trigger tighter restrictions, raising compliance costs for non-U.S. fabs. While ASML remains committed to High-NA EUV through 2030, any alliance between Blue-X and IMEC or foundries in Taiwan, China could divert R&D capital. Within 18 months, prototype validation will determine whether this approach reshapes equipment procurement strategies at Intel and Samsung ahead of schedule.
