Why it matters

Equipment (Front End) — Front-end equipment transforms raw wafers into patterned circuits through deposition, etch, lithography, ion implant, and cleaning steps. The segment contains some of the supply chain's most extreme chokepoints: ASML is the sole supplier of EUV scanners, Carl Zeiss SMT makes every optical column inside them, and TRUMPF supplies the laser sources. Beyond those monopolies, Applied Materials, Lam Research, Tokyo Electron, and KLA collectively cover most other critical process steps and together represent several hundred billion dollars in market value. Zhongke Feice Technology is one of 64 tracked companies in Equipment (Front End).
