Leading semiconductor foundries are confronting unexpected defect rates in early 2-nanometer gate-all-around production runs. The technical bottlenecks threaten to delay the commercial rollout of next-year flagship mobile processors.
Thermal and Lithographic Hurdles
Extreme ultraviolet patterning at sub-2nm scales has introduced parasitic capacitance issues, reducing operational efficiency. Mobile original equipment manufacturers are currently evaluating contingency plans, including extended reliance on 3nm nodes for upcoming device cycles.
