SEMICON China 2026 survey shows China's semiconductor equipment momentum remains relatively strong
After visiting 24 companies at SEMICON China 2026, UBS believes that from 2026 onward, rising capex in China's memory sector, especially DRAM, accelerating localization of wafer fab equipment, and AI-driven demand for back-end packaging and testing will be the main incremental drivers for the industry.
- China's memory capacity expansion may reach around 120-140 kwpm in 2026, with most of the increment coming from DRAM, and it may continue to increase significantly in 2027.
- China WFE vendors are expected to accelerate localization gains at DRAM fabs, and the baseline self-sufficiency target for the CXMT Shanghai plant was cited as 30-40% or higher.
- AI is reshaping back-end packaging and testing demand; 2.5D, HBM TCB, handlers, testers, probers, thermal management, and power semiconductor testing are all benefiting.
- UBS believes the year-to-date pullback in NAURA, AMEC, and ACMR offers an opportunity to accumulate positions, and it maintains Buy ratings on NAURA, AMEC, ACMR, and Changchuan.
Report interpretation
Overview
This report is UBS's industry note after the SEMICON China 2026 Shanghai tour, covering 24 companies across wafer fab equipment, back-end equipment, semiconductor components, raw materials, and OSAT. The core conclusion is that China's semiconductor supply chain is more optimistic about 2026 and beyond memory capex; DRAM capacity expansion and accelerating localization are becoming the main theme for front-end equipment, while AI-related advanced packaging, longer testing time, more complex thermal management, and power semiconductor testing demand are lifting the outlook for back-end equipment.
Core views
The report believes the long-term growth logic for China's semiconductor equipment remains intact. On memory, China's overall memory capacity expansion in 2026 may be around 120-140 kwpm, driven mainly by DRAM, and there may be a further significant increase in 2027; on logic, advanced-node expansion in Shanghai and Beijing is progressing as planned, but visibility in other regions is limited. On localization, DRAM fabs, SPM cleaning, high-selectivity etch, ALD, metrology, and inspection equipment are all making progress. On the back end, AI is driving demand for 2.5D advanced packaging, HBM TCB, handlers, testers, probers, and thermal management equipment, while some traditional packaging is also benefiting from spillover from capacity tightness at overseas leading players.
Analysis framework
UBS cross-validated trends in China's fab capex, equipment localization, back-end packaging and testing, and materials/components demand through company and expert meetings, booth visits, industry feedback, and recent SPE import data, and then summarized segment-specific opportunities based on discussions with company management.

Impact & implications
For investors, the report reinforces the medium- to long-term logic of domestic substitution in China's semiconductor equipment chain and AI-driven back-end demand. Front-end equipment benefits from DRAM expansion, partial progress in advanced logic, and rising localization rates; back-end equipment benefits from higher AI chip testing complexity, advanced packaging expansion, and optical module upgrades; materials and components benefit from local wafer fab supply-security needs and the shift of OEMs toward domestic supply chains. UBS views the recent share-price pullback as an opportunity to build positions, but macro conditions, geopolitics, fab capex, and R&D progress remain the main uncertainties.
Risks
- Macroeconomic conditions and end-market demand weaker than expected.
- Heightened geopolitical tensions, with broader export or supply restrictions.
- The semiconductor downcycle lasting longer than expected.
- Chinese fabs pausing projects or capex coming in below expectations.
- Slower-than-expected R&D progress at Chinese WFE vendors.
- Longer-than-expected validation cycles for equipment and material localization.
- Intensifying domestic competition putting pressure on prices, gross margins, or market share.
What to watch
- Actual 2026-2027 expansion scale at China's DRAM and memory fabs.
- Whether the CXMT Shanghai plant and other DRAM fabs can reach 30-40% or higher localization rates.
- Whether advanced logic capacity expansion in Shanghai and Beijing proceeds as planned.
- Customer validation and order conversion for high-selectivity etch, ALD, SPM cleaning, metrology and inspection, and process control equipment.
- Orders for AI-related 2.5D, HBM TCB, handler, tester, prober, and thermal management equipment.
- Testing equipment demand driven by the migration of optical modules from 400G to 800G/1.6T.
