The quiet engine behind modern chips: ASML’s EUV leap

ASML’s extreme ultraviolet lithography machines—built through decades of risky R&D, strong public-private partnerships, and a vast European supplier network—are the backbone of today’s sub-5nm semiconductors. By outspending rivals, innovating with immersion lithography and the dual-stage TWINSCAN architecture, and forging tight ties with Intel, Samsung, and TSMC, ASML rose from near collapse to global dominance, reshaping the chip industry and geopolitics while pushing Moore’s Law forward toward ever-smaller transistors.
