ASML Is Building a Hybrid Bonding Tool!

Original reporting by SemiAnalysis (Dylan Patel) — Sherry Zhang · published Oct 15, 2026, 3:27 PM EDT

An unannounced ASML die-to-wafer hybrid bonding tool, inferred from patents and its roadmap, would directly threaten incumbent supplier Besi's core business at TSMC and Intel.

Key points

• Patent filings, a news report, and ASML's roadmap suggest it is building a die-to-wafer hybrid bonding tool, unannounced so far. source ↗
• The authors expect advanced logic to adopt first, threatening Besi, whose hybrid bonding business concentrates at TSMC and Intel. source ↗
• The authors say the tool runs dies on a track with independent shuttles, raising station utilization and enabling heterogeneous integration. source ↗
• The authors believe ASML's lithography expertise in alignment accuracy and particle control, bonding's two yield factors, gives it an edge. source ↗
• Remaining challenges include feed-forward metrology, die-to-wafer contact, adapting non-bonding tools for the track, and cleanliness. source ↗

Practical applications

• Investors and strategists with Besi exposure can model revenue at risk if ASML wins die-to-wafer bonding slots at TSMC and Intel.
• Advanced-packaging teams can monitor ASML patent filings and its September photomask initiative for signals of a back-end bonding tool launch.
• Process engineers planning hybrid bonding capacity can compare track-based die handling against incumbent architectures when evaluating future tools.

Context

Hybrid bonding joins dies or wafers directly without solder bumps, and the authors call it the most transformative semiconductor manufacturing advance since EUV. Die-to-wafer bonding, already in volume production for advanced logic, is harder to build than wafer-to-wafer but enables heterogeneous integration. Besi is the incumbent supplier whose hybrid bonding business concentrates at TSMC and Intel, both ASML partners of more than two decades.

What to watch

• An official ASML announcement or a hybrid bonding tool on its public roadmap would confirm the report's thesis.
• Besi order trends at TSMC and Intel, and whether HBM hybrid bonding slips past 2029, will test the competitive claims.
