Applied Materials Buys ASMPT's NEXX for $120 Million, Adding Panel-Level Electrochemical Deposition for AI Chip Packages

The Deal at a Glance

Applied Materials announced on May 3, 2026 that it has signed a definitive agreement to acquire the NEXX business of Hong Kong-listed ASMPT Limited (HKEX: 0522) for $120 million in cash, subject to customary closing adjustments. The transaction is expected to close within the next several months and requires no regulatory approvals.

NEXX, headquartered in Billerica, Massachusetts, will be folded into Applied's Semiconductor Products Group and continue to operate from its current site. ASMPT NEXX President Jarek Pisera will join Applied Materials with the team.

Why Panels, and Why Now

Applied framed the acquisition squarely around AI. As accelerator packages move from 300-millimeter silicon wafer interposers to rectangular substrate panels measuring up to 510 by 515 millimeters or larger, designers can integrate more GPUs, HBM stacks, and I/O chiplets into a single 2.5D or 3D package — pushing more compute and memory bandwidth per package while improving energy efficiency.

"Having NEXX join Applied Materials complements our leadership in advanced packaging, particularly in panel processing — an area where we see tremendous opportunities for customer co-innovation and growth in the years ahead," said Dr. Prabu Raja, President of Applied's Semiconductor Products Group, in the announcement.

What NEXX Brings: Panel-Level ECD

NEXX's core technology is panel-level electrochemical deposition (ECD) — the plating process used to lay down copper interconnect, redistribution layer (RDL) wiring, and through-substrate vias on large-format panels. ECD is the workhorse step that defines fine-pitch I/O on chiplet interposers and substrates.

Applied positions panel-level ECD as the missing piece that lets it deliver "co-optimized solutions for fine-pitch I/O wiring" across the full advanced packaging flow.

How It Slots Into Applied's Packaging Stack

Applied already supplies digital lithography, physical vapor deposition (PVD), chemical vapor deposition (CVD), etch, and eBeam metrology and inspection systems for advanced packaging. ECD has been the obvious gap: copper plating sits on the same panel between PVD seed-layer deposition and CVD/etch dielectric patterning steps.

Adding NEXX gives Applied an integrated PVD-ECD-CVD-etch flow on a single panel form factor, which is exactly what foundries and OSATs need as substrate sizes outgrow 300-millimeter wafer toolsets.

Competitive Read-Through

The NEXX deal is Applied's third advanced packaging move in eight months — following its reported pursuit of BESI's hybrid bonding business and the EPIC partnership announcement with Advantest on April 21, 2026 to bridge front-end manufacturing with back-end test. Together they signal that the equipment majors view advanced packaging as the next leg of the AI capex cycle, after etch and deposition for leading-edge logic and HBM.

For ASMPT, the divestiture removes a sub-scale unit. Industry trade press characterized NEXX as an underperforming asset within ASMPT's portfolio, and the $120 million price tag reflects that.

What This Means for Plasma Processing and Thin Film Deposition

The NEXX deal is a clean signal that thin film deposition is migrating off the round wafer and onto the rectangular panel. For plasma processing equipment makers, that shift is consequential. Plasma etch and PECVD chambers built for 300-millimeter wafers must be re-architected for 510 × 515 mm and larger substrates: larger plasma sources, bigger electrostatic chucks, redesigned gas distribution showerheads, and more demanding uniformity control across a much larger area.

Thin film deposition systems face the same scaling problem. PVD seed layers under copper plating, CVD and PECVD dielectrics for RDL passivation, and ALD barrier layers for fine-pitch I/O all need panel-compatible chambers. Applied's bet is that customers will buy a fully integrated panel line — PVD plus ECD plus CVD plus etch — from a single vendor rather than stitching together point tools. That tilts demand toward suppliers with full-stack panel capability and away from single-step specialists.

The supply chain implications are immediate. Vacuum components, large-area RF plasma sources, larger sputtering targets, panel-format electrostatic chucks, and panel-scale gas delivery and process monitoring all become higher-volume line items. Equipment subsystem suppliers that already serve flat-panel display and large-area solar markets are positioned to win share as the AI packaging panel transition accelerates over the next 24 months.
