Why 193 nanometer immersion lithography remains the industry's true workhorse
While extreme ultraviolet lithography captures the headlines, 193 nanometer immersion lithography has quietly powered the semiconductor industry for two decades. This video explores the technical challenges and engineering breakthroughs that allowed this technology to push beyond its expected limits and remain essential for leading-edge manufacturing.
Emerging in the early 2000s, 193 nanometer immersion lithography—often referred to as 193i—fundamentally changed how chips are printed. By introducing a liquid medium between the lens and the wafer, engineers were able to achieve higher resolution than traditional dry lithography allowed.
Despite the allure of newer extreme ultraviolet (EUV) systems, 193i remains a foundational technology. It continues to serve as a core component in many of today's most advanced process nodes, proving that incremental innovation can sustain industry progress far longer than initial projections suggested.
