What is WFE (wafer fab equipment)?
Wafer fab equipment (WFE) is the machinery used to process wafers inside a chip factory, including lithography, deposition, etching, cleaning, inspection and metrology tools. WFE spending is a common measure of the size of the chip equipment market.
Why it matters for investors
WFE spending follows chipmakers’ capital expenditure plans, which depend on expected demand, technology transitions and government policy. Equipment makers often give their own view of the WFE market with their results.
Changes in which technologies need the most new tools, such as gate-all-around transistors or HBM, shift spending between equipment types and suppliers.
