Galloping War Horse (戰馬圖), by Xu Beihong (徐悲鸿), 1942
Its forward momentum and concentrated force mirror the core argument of this essay: China’s semiconductor equipment industry is advancing not through a single breakthrough, but through the coordinated acceleration of fabs, equipment makers, engineers, and industrial capital.
CXMT is about to go public soon. It is likely to become one of China’s largest semiconductor companies, and perhaps the most important company in China’s semiconductor industry for quite some time. Its significance is not only that China finally has a company genuinely entering the global DRAM club. Nor is it only that China is, for the first time, creating a global-scale variable in a memory-chip market defined by extreme capital intensity, technological difficulty, and cyclical volatility.
More importantly, CXMT’s expansion will reshape the demand structure of China’s upstream semiconductor industry. DRAM manufacturing is not an isolated link. It requires sustained capital expenditure, sustained equipment purchases, continuous process migration, and continuous materials consumption. It also requires long-term production-line validation for suppliers of etching, deposition, cleaning, CMP, thermal processing, inspection, packaging and testing, and key materials.
This is the part I care about most. CXMT’s listing is important, of course. But what is more worth watching is which Chinese semiconductor equipment and materials companies it will pull into real production lines, real customers, and real process feedback. Semiconductor equipment and materials cannot mature only through laboratories, subsidies, or policy documents. They must be used, challenged, and validated repeatedly by major customers before they can truly move from “domestic and usable” to “domestic and trusted.”
So this essay is not only about CXMT. It is about a larger question: as China finally produces a global-scale DRAM manufacturing platform, which upstream links will be pulled into higher-intensity mass-production validation? Which equipment companies will benefit? Which materials segments will be pulled forward? Which bottlenecks will still be exposed? CXMT’s expansion may become the key industrial site where China’s semiconductor equipment and materials sectors enter their next stage.
1. The Equipment Field Behind a DRAM Company
Over the past few years, when the outside world discussed China’s semiconductor industry, attention often concentrated on lithography machines, export controls, and advanced process nodes. These are certainly important, but they do not fully explain what is changing inside China’s semiconductor industry. The real field worth observing is actually inside wafer production lines, equipment introductions, yield-validation rounds, and repeated process-feedback cycles.
Recent Chinese industry-media coverage around CXMT offers exactly such a window. In its report The CXMT Effect: The “Friend Circle” of China’s “Hynix”, Economic Observer placed CXMT at the intersection of the global DRAM cycle and the reorganization of China’s equipment supply chain. The phrase “friend circle” in the title is interesting. It is not merely a supplier list in the ordinary sense. It is a forming industrial chain group: downstream memory manufacturing expansion is pulling etching, deposition, cleaning, CMP, heat-treatment, inspection, packaging-and-testing equipment, and key materials companies into a higher-intensity mass-production validation field.
This is exactly what China Industry Signals should record: Chinese industry media is no longer only discussing whether a Chinese DRAM company can list or become profitable. It is observing how that company becomes a traction engine for an equipment ecosystem.
CXMT’s own transformation is already striking enough. On May 17, the company updated its STAR Market IPO prospectus; on May 27, its STAR Market IPO was approved by the listing committee. According to the prospectus and media reports, CXMT plans to raise RMB 29.5 billion, making it the second-largest IPO in STAR Market history after SMIC. China Securities Journal stated that since its establishment in 2016, CXMT has broken through key core DRAM technologies and achieved commercial mass production, filling the gap in mainland China’s DRAM products in the global market. According to Omdia data, by capacity, shipments, and sales, CXMT has become China’s No. 1 and the world’s No. 4 DRAM manufacturer.
Even more striking is the change in its financial performance. Economic Observer reported that CXMT achieved revenue of RMB 50.8 billion and net profit attributable to shareholders of RMB 24.76 billion in the first quarter of 2026, and expects net profit attributable to shareholders in the first half of 2026 to reach RMB 50 billion to RMB 57 billion, with first-half revenue reaching RMB 110 billion to RMB 120 billion. For a DRAM company that had long been in the investment, loss-making, and catch-up stage, this means it is no longer merely a “strategic project.” It is beginning to enter a real commercial cycle.
The truly important point is that a downstream manufacturing platform like CXMT is pushing China’s semiconductor equipment companies from exhibition halls into production lines.
The harshest part of the semiconductor equipment industry is that equipment is not successful simply because it has been built. It must enter production lines, run processes, pass validation, operate stably, accumulate data, undergo repeated modification, and ultimately be purchased continuously by customers. Many countries can build laboratory prototypes or small numbers of engineering machines. But without sufficiently strong domestic manufacturing customers, it is difficult to form an equipment-iteration loop. Equipment capability formation requires downstream major customers to provide real problems, real orders, and real tolerance space for iteration.
2. CXMT Is the Most Important Validation Field
DRAM is one of the best product categories for observing equipment capability in semiconductor manufacturing. It is large in scale, capital-intensive, process-repetitive, strict on yield, and requires continuous iteration from one product generation to the next. Unlike some niche chips that can be supported by small amounts of specialized demand, once the DRAM industry enters an expansion cycle, it directly creates large-scale equipment procurement and process-validation demand.
China Securities Journal noted that CXMT adopted a “leapfrog R&D” strategy, completed mass production from its first-generation process technology platform to its fourth-generation process technology platform, and achieved product coverage and iteration from DDR4 and LPDDR4X to DDR5 and LPDDR5/5X. This shows that CXMT is not staying on one mature product. It is rapidly crossing product generations. For equipment suppliers, this means validation pressure will keep escalating: equipment that can satisfy one generation of DRAM today may not satisfy the next generation tomorrow; equipment that is stable on mature nodes today may soon face requirements for higher aspect ratios, better thin-film uniformity, stricter defect control, and higher production-stability demands.
This also explains why the “CXMT effect” is not only an order effect, but also a learning effect. What equipment companies truly need is not one-off procurement, but continuous production-line feedback. Etching equipment needs to understand process windows under different materials, structures, and aspect ratios. Deposition equipment must repeatedly balance thin-film uniformity, particle control, stress control, and throughput. Cleaning equipment must handle contaminants, particles, and residues after complex processes. CMP equipment must find a stable combination among planarization, defect rates, consumables, and throughput. None of these capabilities can be designed once and for all in a laboratory. They are ground out through continuous feedback inside fabs.
This is also one of the capabilities China’s industrial system has long been good at: using sufficiently large production sites to turn technical problems into engineering problems, and then using continuous iteration to turn engineering problems into industrial capability.
Economic Observer called CXMT China’s “Hynix,” which is of course a communicable phrase. But from an industrial-system perspective, the more accurate observation is this: CXMT is becoming the anchor customer of China’s memory-equipment ecosystem. It is not merely buying equipment. It is helping equipment companies obtain the scarcest asset: mass-production scenarios.
3. The First Layer of the “Friend Circle”: Etching and Thin-Film Deposition
Inside the CXMT chain group, etching and thin-film deposition equipment attract the most attention. The reason is simple: these two links are technologically difficult, high in value, strongly process-related, and have long been key areas dominated by international equipment giants.
Economic Observer and other industry reports have all mentioned NAURA as one of the most important domestic equipment companies in CXMT’s supply chain. NAURA’s product lines cover etching, thin-film deposition, heat treatment, cleaning, ion implantation, and other links. It has already developed from a single-point equipment company into a platform-based equipment company. Recent industry reports noted that in 2025, NAURA’s etching and thin-film deposition equipment revenue each exceeded RMB 10 billion, while shipments of PVD equipment and vertical furnaces each exceeded 1,000 units.
This type of data is important. For semiconductor equipment companies, the hardest threshold to cross is often not from 0 to 1, but from 1 to 1,000. The first machine can be an engineering breakthrough; ten machines can be reference customers; hundreds or thousands of delivered machines mean that supply chain, manufacturing, service, spare parts, software, field-engineer systems, and customer trust are all beginning to take shape. In the equipment industry, delivery volume itself is part of capability.
NAURA’s significance is not only one or two product breakthroughs. It increasingly resembles a platform company inside China’s equipment industry: etching, PVD, CVD, ALD, oxidation and diffusion, annealing, cleaning, heat treatment, and other links are continuously expanding. This platform capability is extremely important, because large fabs do not only need one piece of equipment. They need a set of equipment systems that can cooperate with each other, adapt to process flows, and provide long-term service capability.
AMEC represents another path: sustained depth in the key etching link. Recent industry reports have repeatedly mentioned AMEC’s breakthroughs in ultra-high aspect-ratio etching. Its independently developed equipment has already put more than 300 reactors into mass production, and its next-generation 90:1 low-temperature etching machine and second-generation ICP etching equipment have achieved 90:1 and 140:1 etching results respectively.
These are highly important in DRAM and 3D memory structures. High aspect-ratio etching means etching very deep, very vertical, and very uniform trenches or holes inside extremely narrow nanoscale structures. The higher the aspect ratio, the more difficult the process. Plasma control, sidewall morphology, selectivity, bottom damage, micro-loading effects, and etch uniformity all have to be solved together. When a piece of equipment can operate stably in high aspect-ratio structures, it means it has entered the core battlefield of advanced memory processes.
This is why CXMT’s expansion is especially important to a company like AMEC. An advanced DRAM production line is not a display window. It is an examination site. Equipment parameters can be written into PowerPoint slides, but process stability must be proven inside the production line.
4. The Second Layer: Cleaning, CMP, and Process Stability
If etching and deposition determine whether many key structures can be formed, then cleaning and CMP determine whether those structures can stably enter the next process step. Many external narratives like to reduce semiconductor manufacturing to a lithography-machine problem. But in real wafer manufacturing, cleaning, planarization, heat treatment, thin films, etching, and metrology/inspection form a highly coupled process network.
In recent industry reporting on domestic equipment “entering the second half,” one repeated judgment is that CMP and cleaning equipment have relatively higher localization; etching and thin-film deposition are penetrating rapidly; while metrology/inspection, coating/developing, and some high-end core components remain weak links.
Hwatsing is the representative company for CMP equipment. CMP is not as easy for external public opinion to understand as lithography, but it is extremely important for advanced processes. Wafer manufacturing does not complete all structures on a single plane. It repeatedly deposits, etches, fills, polishes, then deposits and etches again. After each layer of material is formed, the surface must be planarized; otherwise, subsequent lithography, deposition, and etching will all be affected. The more complex DRAM structures become, the higher the requirement for planarization.
ACM Research Shanghai represents cleaning and wet-process equipment. Cleaning equipment appears extremely frequently in semiconductor processes. After almost every several process steps, cleaning is needed to remove particles, metal contamination, organic residues, etching byproducts, or other contaminants. The more complex advanced processes become, the more cleaning steps are required, and the more important defect control becomes. Cleaning is not simply “washing something clean.” It means controlling defect rates without damaging fine structures, introducing new contamination, or destroying material interfaces.
This is why China’s equipment localization cannot only look at the most eye-catching equipment. A country’s semiconductor equipment capability is not determined by a single flagship machine, but by the coordinated stability of many pieces of equipment across the entire process chain. If cleaning, CMP, heat treatment, etching, deposition, or inspection is unstable at any link, the final result will show up in yield.
A DRAM production line like CXMT’s provides exactly the real-pressure environment these equipment companies need. It is not a university experimental line, not a pilot demonstration line, and not an engineering project running only a few demo wafers. It needs stable shipments, cost control, international competition, and customer requirements for reliability and consistency. Such scenarios force equipment companies to move from “usable” to “good,” and then from “good” to “continuously mass-producible.”
