This cascades upward to materials suppliers and downward to OSATs, forcing ecosystem-wide tooling upgrades. However, tightening U.S. export controls are pushing customers in Taiwan, China and mainland China toward localization, raising Onto’s compliance overhead and limiting market access. Competitors like KLA and Nova, entrenched in gate-all-around metrology, may respond by bundling inspection tools with process control suites to undercut Onto’s panel-level packaging foothold.
