KLA Corporation

Semiconductor manufacturing at advanced nodes (3nm, 2nm, and below) requires an exponentially larger number of inspection steps per wafer because smaller feature sizes mean tinier defects can destroy yield. Process control intensity — the share of total fab capital expenditure allocated to inspection and metrology equipment — rises as chipmakers push to smaller nodes. TSMC's most advanced fabs spend a meaningfully higher fraction on process control than previous-generation facilities, and this structural trend is not reversing.

KLA dominates this category with estimated 50-60% market share in wafer inspection and an even higher share in advanced reticle inspection (the masks that pattern wafers). Unlike etch or deposition equipment where AMAT and LRCX compete, there is no credible alternative to KLA at advanced logic nodes. This captive position means KLAC's revenue is closely tied to advanced logic wafer starts — not cyclical memory capex — which provides more stability than peers during memory downturns.

KLAC is most correlated with advanced logic capex (TSMC, Intel Foundry, Samsung Logic) rather than memory capex. This distinction matters because advanced logic spending has been relatively insulated from the memory downcycles that periodically crushed LRCX and MU. When traders compare KLAC against LRCX, the key question is whether the equipment cycle is driven by logic AI infrastructure (favors KLAC more) or memory recovery (favors LRCX more) — often both are at play simultaneously.

KLAC's ~60% gross margin is 10-15 percentage points higher than its semiconductor equipment peers, which means it tends to trade at a premium multiple relative to the SOXX. When the semiconductor sector corrects, KLAC may hold better than memory equipment names due to its higher service revenue mix and more stable logic exposure. During bull cycles in semis, however, LRCX and AMAT often outperform KLAC from a price perspective due to their higher revenue leverage to new capacity build-outs.
