KLA Corporation (KLAC)

KLA Corporation is the dominant provider of semiconductor process control and inspection equipment — the systems that detect defects and measure critical dimensions during chip manufacturing. As AI chips push to the most advanced process nodes (3nm, 2nm, and beyond), the tolerance for manufacturing defects shrinks to atomic scales. KLA's inspection and metrology tools are essential for ensuring that the billions of transistors on each AI GPU function correctly. Without KLA's equipment, chipmakers like TSMC, Samsung, and Intel cannot achieve the yields necessary to make advanced AI chip production economically viable.

KLA holds approximately 55% market share in semiconductor process control, a position built over decades of technology leadership and deep customer integration. The company's Voyager and eStar inspection platforms use advanced optics, electron beams, and increasingly AI-powered algorithms to detect defects smaller than a single nanometer. As manufacturing complexity increases with each new node, the number of inspection steps per wafer grows — directly expanding KLA's addressable market. The company's services business provides stable recurring revenue from its massive installed base of equipment operating in fabs worldwide, representing approximately 25% of total revenue.
