Advanced Semiconductor Nodes Intensify Plasma Etching Xenon Use
Leading-edge semiconductor manufacturers are increasingly specifying xenon-based plasma chemistries for etching processes at advanced process nodes, where xenon's properties offer meaningful advantages over alternative etching gases for specific critical layers. As fabs continue migrating toward smaller node sizes, per-wafer xenon consumption is rising even before accounting for overall wafer volume growth, compounding total demand growth beyond what unit volume expansion alone would suggest. Semiconductor manufacturers are increasingly securing dedicated long-term xenon supply agreements directly with gas majors to protect against allocation risk during periods of tight global supply. This dynamic is expected to intensify as node sizes continue shrinking further.
