Zhongyong Technology's Intelligent Equipment: Transforming Semiconductor Maintenance from Reactive Firefighting to Proactive Prevention​

Zhongyong Technology has introduced an intelligent equipment agent that transforms semiconductor operations and maintenance (O&M) from reactive firefighting to proactive risk prevention. Addressing critical challenges like high reliability demands, data silos, talent shortages, and rising costs, the solution leverages large-scale sequence models and knowledge computing engines to create a self-aware, autonomous "digital O&M entity." This system continuously monitors equipment in real time using multi-source data (sensors, logs, manuals), identifies anomalies, locates root causes, and enables automated fault handling reducing repair times by over 50% for low-risk issues and offering human-machine collaboration for high-risk cases.


Unlike simple algorithm overlays or automated rule upgrades, Zhongyong Technology's intelligent equipment agent is a "digital operation and maintenance entity" with autonomous understanding, logical reasoning, and implementation capabilities. It can integrate multi-source time-series data such as equipment sensor data and operating parameters, as well as business knowledge such as massive logs, operation and maintenance manuals, and process specifications to conduct unified modeling and analysis. It breaks through the limitations of traditional monitoring tools that "passively receive alarms," continuously sensing and dynamically analyzing equipment status 24/7, and accurately identifying anomalies and locating the root cause of faults from massive and complex data.

Addressing the high-frequency pain points in semiconductor operations and maintenance, the intelligent equipment agent establishes a complete intelligent closed loop encompassing "perception-analysis-response-evolution," directly addressing the industry's core needs:

1. Break through alarm storms: By using techniques such as clustering integration and time sequence alignment to reconstruct the abnormal evolution process, more than 90% of invalid alarms are filtered out, helping engineers quickly pinpoint the source of the fault and significantly improve fault response efficiency;

2. Efficient Fault Handling: For low-risk faults, the entire process of "identification - solution matching - execution - effect confirmation" is fully automated, reducing repair time by more than 50%; for high-risk faults, precise human-machine collaborative decision support is provided, significantly improving equipment uptime.

3. Continuous self-evolution: Each operation and maintenance event will automatically accumulate experience, transforming unstructured fault cases and practical processes into standardized knowledge assets, making the system more intelligent with use and adaptable to more complex operation and maintenance scenarios.

The system reduces O&M costs by over 30% and boosts equipment uptime by ~5%. By standardizing and systematizing maintenance processes, it minimizes reliance on senior engineers and advances semiconductor O&M toward intelligence, scalability, and sustainability. Zhongyong plans to expand this technology into advanced manufacturing, supporting long-term digital transformation in the industry.

Domestic semiconductor electroplating technology breaks through bottlenecks! Zunheng Semiconductor's 2.7% uniformity index ranks among the world's top tier.​

Zunheng Semiconductor has achieved a major breakthrough in independent innovation in advanced packaging electroplating technology, successfully controlling electroplating uniformity at 2.7% exceeding the global high-end standard of 3% and surpassing the mainstream level of 5%. This marks the first time a domestic company has reached world-leading performance in this core technology, breaking overseas monopolies and positioning China’s semiconductor equipment firmly among the global elite.

Advanced packaging is vital for manufacturing high-performance chips like AI processors and high-end memory. Electroplating uniformity directly affects chip yield, signal stability, and thermal reliability making it a critical technical challenge. Historically, only top international firms could meet the 3% standard, while domestic players lagged significantly.

Zunheng’s success stems from its proprietary ion-exchange membrane segmented anode technology, which reduces edge effects in large substrates by precisely controlling the anode region. Combined with an intelligent closed-loop control system that monitors and adjusts plating thickness in real time, it achieves micron-level precision. Enhanced by high-precision flow field simulations (tens of thousands of iterations) and custom additive formulations, the solution ensures consistent ion distribution and coating quality across 8-inch and larger substrates.


The technology has already secured multiple core patents and is now in full commercialization—undergoing customer validation and entering mass production. It improves chip yield by over 15% compared to traditional methods and reduces failure risks caused by uneven plating, providing critical support for large-scale AI and advanced packaging manufacturing.

Industry experts view this as a pivotal milestone: China has transitioned from "following" to "keeping pace" in core advanced packaging equipment. This leap strengthens domestic self-reliance in high-end chip production and bolsters the resilience of China’s semiconductor industrial chain.

The equipment will initially serve leading Chinese companies in AI and advanced packaging, accelerating the commercial deployment of domestically developed high-performance semiconductor devices.

Honestly, the grammar of that translation is confusing. Maybe it sounds better in Korean but whatever Google Translate is saying is confusing because they were talking about D1x yield then suddenly jumps to D1a.

From what I understand, they are comparing the mature processes of CXMT versus their Korean counterparts and stating that the yield of mature process of CXMT (D1x) is 42% below mature process (D1a) of Korean companies and around 50%.

D1a is a 10nm process, so that explains D1x. CXMT was doing D1x several years ago and it should be producing 18nm at pretty high yield now.

More and More Chinese Equipment Companies Are Increasing Their Ranks As Top Suppliers.​

This collective ascent is widely viewed as a direct response to US-led export controls on advanced semiconductor technologies, which catalyzed China's drive for greater self-sufficiency in chipmaking tools.

Roger Sheng, vice-president of research at US market research company Gartner, said: "It's fair to say that Chinese companies' technological gap with international industry leaders is continuously narrowing. This progress has provided strong support for domestic chip manufacturers in their technological upgrades and production expansion efforts, even amid restrictions on access to US technology and equipment."

The manufacturing of advanced chips involves over 1,000 process steps, each requiring specialized equipment. Chinese suppliers can now cover equipment for almost every stage, including deposition, etching and cleaning. This burgeoning ecosystem includes a wave of emerging startups, experts said.

Yin Zhiyao, chairman and general manager of AMEC, said at a meeting in May 2025 that the company's product portfolios include 30 percent of all the integrated circuit equipment categories, and it aims to collaborate with partners to offer 60 percent of all high-end IC equipment categories over the next five to 10 years.

Yin said that AMEC would soon complete the development of more than 20 types of thin-film equipment that are subject to international export restrictions to China, and the company aims to finish the development of nearly 40 thin film equipment by 2029.

China's massive domestic market, now the world's largest for chipmaking equipment, also provides a powerful launchpad. The global semiconductor industry association SEMI, which has more than 3,000 member companies, estimated that worldwide sales of semiconductor manufacturing equipment would reach $133 billion in 2025, surpassing the previous record of $104.3 billion in 2024 and setting an all-time high.
