KLA is the dominant process-control company in chipmaking — its tools find defects (inspection) and measure dimensions (metrology) across the fab, so chipmakers can keep yields high as features shrink. It holds roughly half the process-control market and over 85% of optical wafer inspection, selling to TSMC, Samsung, Intel, Micron and SK Hynix. Complementary to ASML's lithography and largely distinct from Lam/AMAT's process tools, KLA rides the leading-edge, advanced-packaging and AI build-out.

KLA inspects and measures — it doesn't make chips

KLA sits at the equipment stage beside ASML, Applied Materials and Lam. Its tools don't build transistors — they find defects (inspection) and measure dimensions (metrology) so fabs can keep yields high as features shrink. Complementary to ASML's litho and largely distinct from Lam/AMAT's process tools, though AMAT also competes in metrology.
