KLA Corporation dominates the process control segment of semiconductor manufacturing — the inspection and metrology tools that detect defects and measure critical dimensions at every stage of chip production. With approximately 50% market share in wafer inspection and metrology, KLA's tools are a mandatory part of any advanced fab's quality control. Without KLA's defect detection systems, fabs cannot achieve the yield rates necessary for profitable production. The company's dominance makes it a chokepoint: any fab building leading-edge chips at 7nm or below is dependent on KLA equipment, and export restrictions limit its ability to supply advanced process control tools to China.
