China’s semiconductor industry is moving from policy to industrial reality. Backed by long-term state funding and increasingly forceful demand-side mandates, the sector has become a focal point of global technology competition. The launch of the USD 47.5 billion Big Fund III in 2024 underlines the scale and duration of this commitment, extending China’s semiconductor strategy well into the 2030s.

The largest semiconductor companies in China, including SMIC, JCET, NAURA Technology Group, HiSilicon, and Hua Hong Semiconductor, are helping China’s semiconductor market exceed USD 506 billion by 2032, growing at a CAGR of 11.18%.

This article profiles the top 10 semiconductor companies in China in 2026, examining their roles across design, manufacturing, equipment, and packaging.

List of the Top 10 Largest Semiconductor Companies in China 

SMIC (Semiconductor Manufacturing International Corporation)

Semiconductor Manufacturing International Corporation (SMIC) is China’s largest semiconductor company and most advanced pure-play semiconductor foundry, and a cornerstone of the country’s domestic chip manufacturing strategy. Partially state-owned and publicly listed, SMIC focuses primarily on serving the Chinese market rather than global customers, distinguishing it from peers such as TSMC.

SMIC manufactures chips for fabless semiconductor companies, major consumer electronics brands, and strategically important, government-backed projects. Its customer base includes leading Chinese technology firms such as Huawei, Xiaomi, and Alibaba.

From a technology perspective, SMIC offers integrated circuit (IC) manufacturing services across a wide range of process nodes, from mature 350nm technologies to advanced 7nm processes. The company is also actively working on 5nm fabrication to narrow the technology gap with global leaders.

In line with broader consolidation trends in China’s semiconductor industry, SMIC announced in September 2025 that it plans to acquire full ownership of Semiconductor Manufacturing North China (Beijing) Corporation (SMNC).

JCET (Jiangsu Changjiang Electronics Technology)

JCET Group is the largest Outsourced Semiconductor Assembly and Test (OSAT) company in mainland China and the third-largest globally. Publicly listed and headquartered in Jiangyin on China’s eastern coast, JCET provides advanced back-end manufacturing services to customers worldwide.

The company offers an end-to-end portfolio of integrated circuit manufacturing and technology services. These include semiconductor package integration design and characterization, research and development, wafer probing, wafer bumping, package assembly, final testing, and drop shipment to global vendors. This turnkey capability allows customers to streamline product development and accelerate time to market.

As one of the largest semiconductor companies in China, JCET’s technologies support a broad range of applications across mobile devices, communications infrastructure, computing, consumer electronics, automotive, and industrial systems. Its technical strengths span advanced wafer-level packaging, 2.5D and 3D packaging, System-in-Package (SiP), and high-reliability flip-chip and wire-bonding solutions.

To support innovation and scale, JCET operates two R&D centers in China and South Korea, alongside six manufacturing facilities across China, South Korea, and Singapore.

NAURA Technology Group

NAURA Technology Group is China’s largest semiconductor equipment manufacturer and one of the most important suppliers globally. The company, headquartered in Beijing, provides core process equipment used across integrated circuit production, including etching, physical and chemical vapor deposition (PVD/CVD), cleaning, and thermal processing tools.

Beyond IC manufacturing, NAURA has built a diversified equipment portfolio including flat-panel display manufacturing, photovoltaic solar cells, and lithium battery production, allowing the company to benefit from broader clean energy and electronics demand cycles. 

NAURA also produces precision electronic components, including resistors, capacitors, and crystal devices, further strengthening its industrial footprint. In 2024, the company ranked sixth among the world’s top semiconductor equipment vendors by revenue, up from eighth the previous year.

HiSilicon (Huawei Technologies)

HiSilicon is Huawei’s in-house, fabless semiconductor design arm and one of the most strategically important chip companies in China. Wholly owned by Huawei and headquartered in Shenzhen, HiSilicon focuses on designing high-performance system-on-chips (SoCs) and processors for smartphones, telecommunications infrastructure, artificial intelligence, IoT, and other advanced applications.

Operating under a fabless model, HiSilicon designs chips but outsources manufacturing to external foundries. The company licenses key CPU architectures from ARM Holdings, including Cortex-A and Cortex-M series cores, and integrates Mali GPUs. It has also licensed graphics technology from Vivante, enabling competitive in-house SoC development across performance tiers.

Commercially, HiSilicon captured 12% of the global premium Android smartphone SoC market in 2024, up from 8% in 2023, an impressive gain in a segment dominated by Qualcomm, which still holds a majority share.

Hua Hong Semiconductor

Hua Hong Semiconductor is China’s second-largest semiconductor foundry and ranks among the world’s top ten semiconductor companies. Established in 1996 and headquartered in Shanghai, the company was founded as part of China’s national strategy to build a competitive domestic integrated circuit (IC) manufacturing base.

Unlike SMIC, which targets leading-edge logic nodes, Hua Hong has built its strength in specialty semiconductor manufacturing, with a particular focus on 8-inch wafer production and differentiated processes. It operates under a dual strategy combining “8-inch + 12-inch” manufacturing with “Specialty IC + Power Discrete” technologies.

Operationally, Hua Hong runs three 8-inch wafer fabs in Shanghai’s Jinqiao and Zhangjiang districts, alongside two advanced 12-inch specialty fabs in the Wuxi National Hi-Tech District. Notably, one of these Wuxi facilities is the world’s first 12-inch power semiconductor foundry. 

Shanghai Huahong Grace Semiconductor Manufacturing Corporation, Hua Hong Semiconductor (Wuxi) Limited, and Hua Hong Semiconductor Manufacturing (Wuxi) Co., Ltd. are the subsidiaries of Hua Hong Group.

YMTC (Yangtze Memory Technologies)

Yangtze Memory Technologies Co., or YMTC, is China’s flagship flash memory manufacturer and a central pillar of localized critical semiconductor technologies.

Founded in 2016 and headquartered in Hefei, Anhui, CXMT designs, manufactures, and sells dynamic random-access memory used across smartphones, PCs, tablets, servers, gaming systems, and smart home appliances. 

As a privately owned IDM, the company combines in-house R&D with large-scale manufacturing, enabling it to steadily expand its DRAM portfolio for the consumer and enterprise markets. 

In October 2025, CXMT began mass production of LPDDR5X, a next-generation DRAM standard widely used in high-performance mobile devices and increasingly important for AI workloads. DRAM plays a critical role in artificial intelligence systems by enabling fast data access during model training and inference, making CXMT’s progress strategically significant.

Conclusion

China’s leading semiconductor companies reflect a deliberately constructed ecosystem rather than isolated champions. Foundries such as SMIC and Hua Hong provide manufacturing depth, JCET ensures scale in advanced packaging and testing, NAURA reduces dependence on foreign production tools, and HiSilicon anchors domestic demand through system-level chip design. 

Alongside memory leaders and fabless specialists, these firms collectively support China’s ability to sustain a largely self-contained semiconductor supply chain at mature and mid-range technology nodes.

Looking ahead, the future of China’s semiconductor industry will be shaped by policy persistence, enforcement of domestic demand, and technological adaptation under export controls. While restrictions on EUV lithography may cap leading-edge progress, sustained investment through USD 47 billion Big Fund III, mandatory domestic chip adoption, and rapid growth in AI, EVs, and telecom infrastructure are likely to secure long-term scale and resilience. 

By 2030, China may not dominate the most advanced nodes globally, but it is positioned to control one of the world’s largest and most strategically insulated semiconductor markets.
