The Advancement Path of ChipHuazhang's Domestic EDA Technology​

In 2026, the global semiconductor industry is undergoing an unprecedented "logic explosion," with the AI infrastructure market reaching a trillion dollars in size. Industry competition is shifting from a simple infighting over chip-level "computing power density" to a struggle for certainty in the value chain.

In the era of trillions of transistors, chip design complexity has increased exponentially, while the efficiency of traditional design verification tools has only maintained linear growth. The huge gap between the two is becoming a "black hole" swallowing up chip manufacturers' R&D costs and time to market. Against this backdrop, in the past two years, Chinese EDA company Xinhuazhang has completed its transformation from a traditional chip tool vendor to a system-level productivity engine in the AI era through technological innovation and organizational restructuring.

In response to industry pain points, Xinhuazhang proposed the "EDA 2.0" concept , which breaks away from the traditional positioning of EDA as an isolated link in the chip industry. It reconstructs the system-level design and verification process from the bottom up, promotes the industry's evolution from AI-Driven to Agentic AI , and enables tools to have the ability of intelligent agents with autonomous reasoning and automatic debugging. It realizes the collaborative verification of hardware logic and software before tape-out, which meets the demand of the trillion-dollar AI infrastructure market for the efficiency of whole system-level convergence .

In terms of core technology breakthroughs, Xinhuazhang has deeply applied large language models to the field of formal verification. The intelligent SVA generation tool, jointly developed with leading clients such as ZTE Microelectronics , can automate three layers of verification: syntax, functionality, and quality, thus reconstructing the digital verification production relationship. In an AI inference chip project for a leading internet client, this tool compressed the original three-month verification cycle to three weeks , transforming formal verification from a capability exclusive to senior experts into a standard feature of general development, thereby achieving widespread access to industrial productivity.

On the hardware side, Xinhuazhang also delivered impressive results. In 2025, its hardware emulator shipments exceeded 100 units, achieving large-scale mass production deployment. Furthermore, in the field of intelligent computing chips, it completed a large-scale cascaded deployment of over 40 hardware emulators, setting a record for the scale of domestic hardware simulation systems.
This solved the latency and synchronization problems of ultra-large-scale data interaction, verified the stability and deployment capability of domestic equipment in large-scale computing chip verification, and laid a solid verification foundation for AI infrastructure construction .

The use of domestic chips among domestic OEMs keep increasing.​

Vivo flagship phone is using Huizhi Micro RF chips.​


The n79 band is a key band for 5G/5G-A communication. Its bandwidth is several times or even tens of times that of other commonly used bands. Especially in densely populated areas such as concerts and high-speed rail stations, the difference in experience between using and not using the n79 band is very obvious.

However, due to the additional area and cost required to integrate this frequency band, only a few flagship phones previously supported it. This time, vivo has brought the communication capabilities of its Ultra flagship series down to the X standard flagship version for the first time, demonstrating that vivo is striving to meet the highest specifications in communication details to improve the user experience.

The reason vivo was able to integrate more communication bands into the X300s without sacrificing battery capacity is due to the use of a miniaturized, highly integrated RF front-end module that supports 5G/5G-A n79 bands. Developed by Huizhi Micro, a leading domestic RF front-end chip supplier, this module is 40% to 50% smaller than previous solutions. This allows the X300s to achieve flagship-level communication capabilities within a limited body space, while also leaving more room for improved battery life and performance.

It was this chip that enabled the X300s to be the first to bring Ultra-flagship-level communication capabilities to the standard version of flagship phones—and what it unlocked was far more than just an upgrade in the user experience of a single phone; it was also the beginning of breaking the long-standing "n79 deadlock" that had plagued the industry.

Huatai Gas's revenue reached 1.419 billion yuan in 2025, with the number of import substitution products increasing to 57.​


Huatai Gas reported a total operating revenue of RMB 1.419 billion for 2025, representing a 1.7% year-on-year increase, despite facing industry-wide challenges such as declining prices and increased production capacity. While net profit attributable to shareholders decreased by 26.75% to approximately RMB 135 million due to pressure from traditional fluorocarbon price drops, temporary hydride demand fluctuations, and convertible bond interest accruals, the company successfully optimized its profit structure. Notably, the gross profit margin in the semiconductor application sector rose by about 1.04%, driven by the commercialization of high-margin new products and stable supply capabilities. To reward investors, the company announced a cash dividend of RMB 5.0 per 10 shares.

As a leader in China’s electronic specialty gases sector, Huatai Gas significantly advanced its import substitution efforts, increasing its portfolio of substitute products from 22 at launch to 57 in 2025. More than 20 of these products are now used in 14nm and 7nm advanced process lines, with some reaching 5nm cutting-edge processes, covering over 90% of domestic 8-inch and 12-inch integrated circuit manufacturers. The company capitalized on the structural recovery in the semiconductor industry, particularly the demand surge from AI and data centers, while strengthening its R&D capabilities through the acquisition of Hebi Derui Technology. This move enhanced its integrated production of high-end fluorinated gases, resulting in 270 authorized patents and successful sales orders for new materials like silane and hydrogen bromide.

Strategically, Huatai Gas is pursuing a globalization strategy that combines deep domestic cultivation with overseas expansion, steadily growing its international customer base, including five semiconductor clients in Singapore. To support this growth and ensure supply chain security, the company has optimized its production layout with projects in Jiangxi and Jiangsu, including a 1,764-ton-per-year semiconductor materials project, and improved logistics to achieve one-day delivery within a 200-kilometer radius. Looking forward, Huatai Gas remains committed to the localization of core semiconductor materials, aiming to enhance self-reliance in the industry chain through continued R&D investment and market expansion.​

Study on debris contamination characteristics and control methods of DPP-type EUV light source.​

Abstract​

As a key technology for advanced semiconductor manufacturing, extreme ultraviolet lithography (EUVL) requires high exposure power to achieve high productivity and low cost. Nevertheless, debris-induced contamination and degradation of EUV optics remain a major limitation for lithography efficiency and system stability, especially in discharge-produced plasma (DPP) EUV sources. In this work, we realized the effectiveness of in-situ monitoring and control of debris contamination associated with DPP sources. First, we analyze the material characteristics and deposition behavior of debris through in-situ collection and characterization experiments. By varying exposure conditions, we identify key parameters that influence debris deposition. Furthermore, we evaluate the effectiveness and limitations of cleaning debris with operando-compatible argon (Ar) plasma. Finally, we design a debris mitigation (DM) unit that integrates vacuum differential and debris inhibition functions for the DPP system. This work offers practical strategies to mitigate debris in DPP EUV sources, which is crucial for enhancing their power scalability and operational stability in advanced lithography systems.​
