ASML Ventures into Advanced Chip Packaging to Fuel Future Growth

ASML leverages EUV precision to enter the back-end chip packaging market with hybrid bonding, aiming to create a new growth pillar amid strong core business.

The Dutch semiconductor equipment giant ASML, renowned as the sole producer of extreme ultraviolet (EUV) lithography machines, is charting a new course. The company is developing a hybrid bonding system, marking its strategic entry into the back-end packaging market—a segment where it has previously had no presence.

Strategic Rationale and Technological Edge

This move is driven by the critical role hybrid bonding plays in next-generation chip manufacturing. The technology enables the direct connection of copper surfaces on stacked chips, eliminating the need for the microscopic metal bumps used in conventional processes. The result is significantly denser interconnects and superior electrical performance.

ASML is not building this new system from scratch. Instead, it is leveraging its core competencies. The magnetic levitation technology integral to its EUV machines provides the sub-nanometer alignment precision required for hybrid bonding. For development, ASML is in discussions with long-time suppliers Prodrive Technologies and VDL-ETG as potential partners.

The strategic imperative is clear. Following an analysis of roadmaps from memory chip makers like SK Hynix, ASML's Chief Technology Officer Marco Peters stated that demand for stacking process equipment is "certain." SK Hynix itself forecasts a semiconductor wafer supply deficit exceeding 20% by 2030, indicating sustained tailwinds for equipment manufacturers.

Core Business Strength and Competitive Landscape

While expanding, ASML's core lithography business remains robust. The company reported fourth-quarter 2025 revenue of €9.7 billion, with net bookings reaching €13.2 billion. Of those bookings, €7.4 billion originated from the EUV segment. For the full 2026 fiscal year, management anticipates net sales between €34 billion and €39 billion, with a gross margin projected in the range of 51% to 53%.

The competitive environment in packaging, however, presents a challenge. ASML is a late entrant to a field where companies like Besi and ASMPT are already well-established. Furthermore, Applied Materials has forged a partnership with Besi, underscoring the competitive intensity. ASML must now play catch-up in a domain where rivals possess years of accumulated experience.

From a broader competitive standpoint, Chinese rivals do not yet pose an imminent threat. The most advanced deep ultraviolet (DUV) system developed in China is technically comparable to an ASML machine from 2008, indicating a substantial technology gap.

Market Performance and Future Prospects

ASML's share price has more than doubled since its low in April 2025 and currently trades approximately 7% below its 52-week high. The central question for investors is whether the hybrid bonding initiative can evolve into a genuine second pillar of growth. Its success will largely depend on execution speed in a market where competitors already hold strong positions.
