AMEC Launches Primo Matrix Plasma Wafer Dicing System; First Tool Shipped to a Domestic Packaging Customer, Kerf Down to 5 Microns (November 10, 2026)

Event overview ​

On November 10, 2026, AMEC (Advanced Micro-Fabrication Equipment Inc. China, SSE: 688012) announced through its official WeChat account the release of a new product, Primo Matrix®, a dual-station plasma wafer dicing system, and that the world's first tool had been successfully shipped to a major domestic IC packaging customer.

Several outlets followed the same day with consistent specifications, including Shanghai Securities News (cnstock.com), China National Radio (CNR), Securities Daily and People's Finance. An AMEC representative said the launch and shipment not only broaden the company's product portfolio in advanced packaging equipment but also support the packaging industry's technical push at advanced process nodes.

The wording deserves attention. The announcement says the tool has been "shipped," not "accepted" or "in production." The tool has reached the customer; the customer-side process qualification results, ramp-up status and whether repeat orders follow have not been disclosed.

Key facts ​

Why kerf width is the system's core metric ​

Where wafer dicing sits in the packaging flow determines what its value actually is: not "whether it can cut," but "how much it saves." A wafer holds hundreds to thousands of dies, and the streets between them are the corridors reserved for the blade. Narrower corridors mean more dies from the same area — effective output rises directly. Conversely, the dicing step itself generates heat, mechanical stress and micro-cracks; the rougher the cut, the more yield can bleed out at the very last process step.

That is why the trio of requirements — high precision, low damage, narrow kerf — becomes urgent at advanced packaging. As packaging moves toward multi-die integration, 2.5D/3D stacking, bumping and thin-wafer processes, the dicing step no longer faces a standard-thickness intact wafer but a thinned sheet, a bumped surface, and structures that must avoid mechanical contact stress.

Plasma dicing belongs to the non-contact category: material is removed by plasma etching rather than physically sawn by a blade. AMEC is reusing its Primo TSV® deep-silicon etch technology, which is already in volume production. That matters — an etch capability that has run through volume manufacturing is being ported to a new process step, which carries lower technical risk than starting from scratch.

The three specifications disclosed map onto three distinct constraints: a minimum 5-micron kerf addresses "how much it saves"; support for 25 to 700 microns addresses "thin wafers too"; and dual stations with up to six etch stations addresses throughput. All three must hold simultaneously for a tool to enter a production line rather than remain a lab demonstration.

Reading the three numbers: 5 microns, 25-700 microns, dual stations ​

Start with 5 microns. Kerf width converts directly into wafer area utilization. The company's wording is that the system "can be applied to various kerf widths as narrow as 5 microns, substantially reducing wafer area loss and increasing effective die output." No specific improvement figure and no comparison baseline are given, so only the capability boundary can be confirmed — the output gain cannot be calculated from it.

Next, 25 to 700 microns. This range covers both ultra-thin and conventional wafers. The 25-micron floor means the tool must handle wafers thinned to extreme thinness, precisely the wafers most vulnerable to stress damage under mechanical dicing; the 700-micron ceiling covers conventional thicknesses. The company states this range "applies to dicing after wafer thinning and to multiple advanced packaging processes."

Third, the station architecture. Primo Matrix uses a dual-station etch chamber plus a wafer transfer module and, on the Primo platform, can carry up to six etch stations, "suited to long process times and enabling high-volume production for customers." The phrasing is measured: plasma dicing typically takes longer per unit than mechanical dicing, so throughput is recovered through parallel stations and transfer efficiency rather than per-tool speed. A six-station configuration indicates a tool designed for line throughput, not a single-point process demonstrator.

One point is easy to overlook: the system also offers hard-mask opening etch for dielectric layers. That means it does not only dice — it can handle wafer surface structures with dielectric layers on the same platform, widening the process envelope beyond a single-function tool. For an OSAT, one tool doing two jobs directly affects line layout and purchasing decisions.

The platform logic behind one dicing tool ​

Placed back into AMEC's product sequence, this launch reads more like an outward extension of a platform strategy than an isolated product.

Per the company's disclosure, AMEC has developed 54 high-end semiconductor tools: 26 high- and low-energy plasma etch systems (single-station chambers plus dual-station CCP and ICP tools operable independently), 24 thin-film systems (MOCVD, PECVD, LPCVD, ALD, EPI and others), plus CMP, advanced packaging and optical metrology equipment. On the etch side, coverage spans 65nm to 3nm and beyond; dielectric etch reaches extreme aspect ratios of 60:1 and 90:1, silicon etch reaches 140:1, and the industry-first dual-station ICP etch technology reaches a 0.2-nanometer single-atom level.

The installed base offers another angle: the official release states that, as of end-June 2026, more than 8,800 reaction stations were in volume production across 220-plus lines worldwide; a November 10 Securities Times report separately cites "more than 9,300 reaction stations as of end-September 2026." The two figures reflect different reference dates; this site records both without merging them.

The company's five-year target is to cover about 60% or more of the high-end semiconductor equipment market and 70% or more of the advanced packaging equipment market. Primo Matrix sits in the "advanced packaging" cell, matching the second target. Seen that way, the strategic value of this tool is less about single-unit revenue and more about pushing AMEC's boundary from front-end etch into a critical back-end packaging step.

Impact and limits ​

First, a domestic supplier has entered "dicing," a step in advanced packaging previously served mainly by overseas vendors. Wafer dicing has long been a combined battlefield of blade tools and laser grooving; plasma dicing is a separate technology branch. Entering with in-house etch technology gives AMEC a route-level option rather than a parameter catch-up on an existing route.

Second, advanced packaging is becoming a new growth pool for equipment spending. As the marginal cost of lithographic scaling rises, the industry shifts more value into packaging, lifting demand for dicing, bonding and inspection tools. AMEC broadening its portfolio in this direction is a direct response to that migration.

Third, commercial validation is not finished. First shipment is a starting point; what follows is customer-side process qualification, yield data, and whether volume orders materialize. The release discloses no unit price, order value, customer name or production timeline.

Limits to be explicit about: Primo Matrix's actual dicing yield, throughput (wafers per hour), consumables and maintenance costs, and comparative data against blade and laser dicing are all undisclosed; the specific magnitude behind "substantially reducing wafer area loss" is also not given. The customer is described only as "a major domestic IC packaging customer," unnamed. This site makes no parameter extrapolation or performance forecast.

For financial context: according to Securities Times DataBao statistics, AMEC reported net profit attributable to shareholders of RMB 4.134 billion for the first three quarters of 2026, up about 241.31% year on year, with revenue up 28.08% and R&D spending at roughly 31.20% of revenue; the company drew 257 institutional research visits in the past week. These are media-compiled figures, not the text of a company filing.
