ASML moves beyond EUV into $6B advanced packaging market for AI chips

What's the deal? ASML, the Dutch company with a monopoly on extreme ultraviolet (EUV) lithography machines, is expanding into advanced packaging equipment. Chief technology officer Marco PietersDealroom has a profile for this one. Try Dealroom → told Reuters the company is looking 10 to 15 years ahead, exploring tools that help stack and connect multiple specialised chips — a process critical for AI processors.

The $560 billion company shipped its first advanced packaging scanner, the XT:260, in late 2025. The i-line machine offers up to four times the productivity of existing solutions, according to ASML.

Why now? AI is hungry for computing power, but the biggest bottleneck isn't processing speed — it's getting data from memory to the processor fast enough. Stacking memory chips directly on or next to processors minimises this distance. That requires extreme precision in packaging, with tolerances in the sub-micrometre range.

Moore's Law is also hitting physical limits. Transistors are now so small that further shrinkage faces quantum mechanical problems. The solution lies in building up, not down — combining multiple specialised chips vertically and horizontally.

"Accuracy is becoming more and more important," Pieters said. What was once a low-margin back-end process has become a strategic lever for AI chip performance.

What could go wrong? ASML trades at roughly 40 times forward earnings, compared with Nvidia at about 22 times. Investors have priced in dominance that the company must now deliver in a new market segment.

Competition exists. Dutch firm Besi leads in hybrid bonding machines. American rival Onto InnovationDealroom has a profile for this one. Try Dealroom → has its own packaging lithography tools. ASML is entering their turf.

The packaging equipment market is also much smaller — about $6 billion annually versus $116 billion for wafer fabrication equipment. Moving the needle will take time.

The signal: The boundary between front-end chip manufacturing and back-end packaging is blurring. TSMC, Intel, and memory makers like SK HynixDealroom has a profile for this one. Try Dealroom → are all pushing 3D integration. ASML wants to be indispensable across the entire chain — from exposing transistors to assembling finished systems.

This is diversification, not distraction. With EUV facing long development cycles and export restrictions complicating China sales, advanced packaging offers a fresh growth lever. ASML's shares have gained more than 30% this year on that optimism.
