Semicap — KLA, AMAT, LRCX, and the Picks-and-Shovels Layer
Wafer fab equipment vendors, the China-export-control impact on semicap revenue, and book-to-bill as a leading indicator
If TSMC, Samsung Foundry, Intel, and SMIC are the picks-and-shovels of the digital economy — building the chips that everything runs on — then the semicap industry is the picks-and-shovels of the picks-and-shovels — the companies that design and manufacture the equipment those fabs use to make the chips. The total worldwide WFE (Wafer Fab Equipment) market was approximately $100 billion in 2024 per SEMI World Fab Forecast estimates, distributed across photolithography (ASML monopoly at the leading edge — covered in sc1_l3), etch and deposition (the largest single category, dominated by Applied Materials and Lam Research), metrology and inspection (where KLA holds dominant market share), and a long tail of specialty equipment categories. Five companies — Applied Materials, Lam Research, KLA, ASML, and Tokyo Electron — capture approximately 75-80% of total WFE revenue.
They are the structural beneficiaries of every fab build-out anywhere on earth, the canonical picks-and-shovels exposure to the secular growth in semiconductor demand, and (since October 7, 2022) one of the most policy-sensitive sub-sectors in semis equity investing.
