KLA Corporation
Process control monopoly — inspection and metrology that catch defects
KLA dominates semiconductor process control: optical and e-beam inspection plus metrology tools that detect nanometer-scale defects and measure critical dimensions across the fab. At leading-edge nodes, where a single defect can kill a die, KLA's inspection is effectively mandatory and it holds ~50%+ share of the process-control market. This near-monopoly position makes KLA an essential, hard-to-substitute node in advanced manufacturing, also constrained by China export rules.
