ASM International — the second Dutch semiconductor capital equipment company after ASML, and historically the smaller cousin — has become the anchor supplier of hybrid bonding tools for advanced packaging. The technology is required for the interconnect density that HBM and next-generation logic-memory packages demand, and ASMI has moved from niche vendor to structural supplier. Bookings, backlog and margins have all repriced upward, and the market is now treating ASMI as a genuine second-tier semi cap franchise.
Key takeaways
- ASMI is the anchor hybrid bonding supplier at scale.
- The tool is required for HBM and advanced logic-memory packages.
- Bookings, backlog and margins have repriced.
- The Dutch semi cap franchise is genuinely two-name deep now.
Why hybrid bonding matters
Chip-to-chip interconnect at hybrid bonding density enables architectures that microbumping cannot. The demand is HBM4, chiplets, and logic-on-logic.
- HBM: primary driver
- Chiplets: secondary
- Logic-memory 3D: emerging
- Customer base: TSMC, Samsung, hyperscaler ASICs
What this does to the Dutch cluster
ASML remains the dominant Dutch semi cap name. ASMI is now a second franchise that adds real diversification.
What the competitive landscape shows
A small handful of tool vendors can deliver hybrid bonding at scale — ASMI is one of them.
What could break the trade
A packaging technology pivot that leaves hybrid bonding stranded.

Frequently asked questions
Is ASMI now a competitor to ASML?
No — different tool categories.
Is hybrid bonding durable?
Base case yes, HBM4 and chiplets anchor it.
What is the concentration risk?
A small number of leading-edge customers.
The bottom line
ASM International's hybrid bonding franchise is now the second leg of the Dutch semi cap complex.
