ASML Reportedly Developing Hybrid Bonding Equipment, Besi Stock Drops 3%
nashnova research
A SemiAnalysis report says ASML is building hybrid-bonding tools based on 27 patent filings, threatening Besi's core franchise — Besi fell 3% on the day while ASML rose 1.1%, a split that shows the market is already repricing the packaging battleground.
What happened?
Semiconductor research firm SemiAnalysis published a report analyzing 27 ASML patent filings, concluding that ASML is developing hybrid-bonding equipment — a process that joins two chips face-to-face for advanced 3D packaging.
Besi is the current leader in hybrid-bonding tools. Its shares fell 3% on the news, closing at €158.50.
This means → the market sees ASML's entry as a direct discount on Besi's moat in this space.
What does ASML say?
An ASML spokesperson declined to comment on the report but pointed to a statement from when the company launched its first advanced-packaging tool last year: "We continue to monitor 3D integration trends."
In March, Reuters quoted ASML CTO Marco Pieters saying the company plans to release more packaging tools.
In plain terms = ASML hasn't confirmed anything on the record, but the signals are hard to miss — patents filed, tools shipping, and the CTO on record talking about more.
Why is ASML moving into packaging?
Nick Rossolillo, co-founder of Chip Stock Investor, said packaging is "the next frontier where performance gains can be unlocked," and ASML appears to be building next-generation tools in that direction.
He added that new packaging tools are critical to sustaining the growth that ASML's current high valuation demands.
This means → for ASML, packaging is not a side project — it is a growth imperative to justify the premium the stock already carries.
What does the market reaction tell us?
On the day, Besi fell 3% while ASML rose 1.1% to €1,480 — the two stocks moved in opposite directions on the same news.
This reflects how investors are already pricing ASML's entry: a larger player arriving is read as upside for the entrant and a threat to the incumbent's moat.
Whether Besi can defend its hybrid-bonding lead is now the key variable to watch.
