Wafer Fab Equipment
Tools and precision subsystems that build and measure AI wafers
Where it sits
Feeds: Compute Silicon · Memory & Storage · Networking & Interconnect
Wafer fabs repeatedly pattern, deposit, etch, clean and measure material layers to build logic and memory devices. AI increases demand for advanced transistors, denser DRAM and more complex interconnects. Toolmakers depend on specialized optics, vacuum systems, plasma power and contamination-free handling.
Why now
SEMI forecasts WFE sales of $143.9B in 2026, up 23.1%, with another 21.8% growth in 2027. HBM and leading-edge logic drive spending. China tool substitution and fab licensing restrictions alter regional supplier access while the BIS affiliates rule remains suspended.
Lithography & mask ecosystem
Exposure tools depend on resist processing, precision optics, light sources and defect-free masks. Advanced logic and DRAM require EUV; mature and specialty chips continue to use DUV, while new patterning approaches address selected layers.
