SemiAnalysis said on October 15, 2026, that ASML may be developing a die-to-wafer (D2W) hybrid-bonding tool, drawing that inference from patent filings, roadmap material and earlier reporting. ASML had not announced the tool as of the analysis. Read SemiAnalysis’s analysis. Reuters reported on October 16 that ASML did not confirm the development and declined to comment on the report. Read the Reuters report.
What the reporting says about ASML
SemiAnalysis counted 27 ASML bonding patent families filed between December 2022 and November 2024, most related to D2W bonding. It also cited The Elec reporting that ASML had begun architecture design with Prodrive Technologies and VDL ETG. These reports inform SemiAnalysis’s inference; they do not amount to an ASML product announcement.
The proposed tool is specifically a die-to-wafer bonder: individual semiconductor dies would be bonded to a wafer. The central claim in the coverage traces to SemiAnalysis’s analysis. Investing.com summarized that analysis, while Reuters reported on it; those accounts do not constitute separate technical confirmation.
How SemiAnalysis describes the proposed process
In SemiAnalysis’s interpretation of patent material, each die would travel on an individual holder along a track, passing through inspection, cleaning, plasma activation, metrology and alignment before bonding to a wafer. The analysis suggests that independent shuttles could let stations work concurrently, that adding stations could increase capacity, and that recipes could accommodate different die types.
Those are proposed design possibilities, not measured results. SemiAnalysis identifies alignment accuracy and particle control as potential advantages, while also pointing to engineering challenges involving feed-forward metrology, die-to-wafer contact, adapting non-bonding tools to the track and keeping the process loop clean.
Why a possible tool could matter to Besi
SemiAnalysis describes Besi as the only supplier with D2W tools in volume production and says its logic-bonding business is concentrated at TSMC and Intel. If ASML develops a competing tool, Besi could face a new rival in that segment.
SemiAnalysis expects advanced logic to be the likeliest first application for a prospective ASML tool. Its forecast for D2W bonding in high-bandwidth memory (HBM) is no earlier than 2029, if adoption happens at all.
