China's chip equipment makers ride record AI orders into 2027, but new challenges lie ahead

Order backlogs extending to 2027 signal a structural shift: Chinese equipment vendors are transitioning from demand-takers to capacity-planning gatekeepers. The AI storage and advanced packaging wave multiplies process steps in etch and deposition (HBM layer stacking) while driving volume and ASP growth in cleaning and electroplating (RDL layer proliferation). Yet the binding constraint is not demand—it is the component supply chain. RF generators, precision valves, and specialty gas manifolds remain heavily import-dependent, creating a 12-to-18-month 'lag tax' between booked orders and recognized revenue. Drawing on the 2021 domestic photoresist capacity cycle: every 10-percentage-point gain in component localization lifts equipment-maker gross margins by 3–5 points, but yield-ramp timelines are incompressible. Applied Materials will likely accelerate mid-tier production-line transfers into mainland China by 2026 to blunt share erosion, while Tokyo Electron is more probable to retreat into niche coater segments. The 18-month inflection point is not order volume but the pace of single-point dependency elimination in critical components. Whoever closes the domestic substitution loop on RF and vacuum systems first will convert the 2027 delivery window from a mere revenue event into a margin-locking event.
