US-China AI chip race: Cambricon's first profit lands - AI News
New Post has been published on https://thedigitalinsider.com/us-china-ai-chip-race-cambricons-first-profit-lands-ai-news/
US-China AI chip race: Cambricon's first profit lands - AI News
.pp-multiple-authors-boxes-wrapper display:none; img width:100%;
The US-China AI chip race has entered a new phase as Chinese chip designer Cambricon Technologies reports its first-ever quarterly profit. The milestone emerges against a backdrop of escalating US export controls that have increasingly restricted Chinese companies’ access to advanced semiconductor technology, particularly Nvidia’s sophisticated AI processors.
Cambricon’s breakthrough into profitability signals a significant shift in the US-China AI chip race, transforming from a 2016 startup into China’s most valuable artificial intelligence company, now valued at approximately 300 billion yuan ($41 billion).
While this represents only a fraction of Nvidia’s $3 trillion market capitalisation, it marks China’s growing capability to develop sophisticated AI chips domestically.
The company’s financial turnaround is particularly noteworthy in the context of technological competition between the world’s two largest economies. After years of losses, Cambricon reported its first quarterly profit in the final quarter of 2024, with net profits ranging from 240 million yuan to 328 million yuan, despite posting a 724 million yuan loss in the first nine months.
The market’s response to this shifting dynamic in the US-China AI chip race has been remarkable. Cambricon’s shares on the Shanghai Stock Exchange’s Star Market have surged more than 470% over the past year, climbing from 120.80 yuan to 695.96 yuan.
The company projects a 70% revenue increase to 1.2 billion yuan in 2024, driven by China’s aggressive buildup of computing infrastructure to support its AI ambitions.
At the technical level, Cambricon has positioned itself as China’s answer to US chip restrictions with its 7-nanometre AI chips. The company’s flagship Cambricon-1A processor has gained significant traction in the domestic market, particularly in products from major technology companies like Huawei Technologies.
The stakes in the US-China AI chip race continue to rise, with analysts at Changjiang Securities projecting that China’s AI semiconductor market will reach 178 billion yuan by 2025. Beijing’s push for semiconductor self-sufficiency and increasing investments from domestic technology companies in AI infrastructure are fueling this growth.
Recent US regulations announced in January 2025 have intensified the race, restricting Chinese access to advanced AI technology and limiting it to American companies and their allies. In response, major Chinese technology companies are investing heavily in domestic computing infrastructure.
ByteDance, TikTok’s parent company, has committed 4.5 billion yuan to a new computing centre in Datong City, Shanxi province. This highlights the growing market opportunity for domestic chip manufacturers.
While Cambricon’s progress represents a significant advancement in the US-China AI chip race, challenges remain. The company must continue to narrow the technological gap with international competitors while maintaining its growth trajectory.
However, supportive government policies and growing domestic demand provide a favourable environment for continued development. Cambricon’s inclusion in the SSE 50 Index, which tracks the Shanghai Stock Exchange’s most valuable companies, underscores its strategic importance to China’s technology sector.
As global tensions persist and access to foreign technology becomes more restricted, developing domestic AI chip capabilities has become increasingly important for China’s technological advancement and economic security.

SiC Seeding for Sustainable Green Energy: An Overview of SiC Crystal Growth and Wafer Processing
Silicon carbide (SiC) is rapidly emerging as a game-changing material in the semiconductor industry. Its superior performance in high-power applications — such as electric vehicles, power grids, and renewable energy — sets it apart from traditional silicon-based solutions. With a wide bandgap, high electron mobility, and excellent thermal conductivity, SiC enables more efficient power devices, reducing energy loss and enhancing performance.
This article explores SiC crystal growth and wafer processing techniques, shedding light on the challenges and innovations driving the scalability and cost-effectiveness of SiC semiconductor manufacturing.
1. Fundamentals of SiC Crystal Growth and Material Properties
1.1 SiC Requirements
SiC is integral to modern power applications due to its exceptional properties, including a bandgap three times wider than silicon and a significantly higher critical electric field. These characteristics enable SiC-based power devices to operate at higher voltages and temperatures while reducing power losses and heat dissipation requirements.
Orbit & Skyline Semiconductor Fab Services specializes in precision processing and advanced fabrication solutions tailored for SiC technology, ensuring high-performance outcomes for semiconductor manufacturers.
1.2 SiC Crystal Structure
Silicon carbide exists in over 250 polytypes, each with unique electrical properties. Among them, 4H-SiC is the most favored due to its high electron mobility, breakdown voltage, and thermal conductivity. However, growing SiC crystals at industrial scales presents significant challenges, primarily due to the high processing temperatures (exceeding 2000°C) and the slow growth rates required to maintain quality and minimize defects.
1.3 SiC Boule Growth Methods
The semiconductor industry primarily employs three major methods for growing SiC boules, with the Physical Vapor Transport (PVT) method being the most prevalent. PVT relies on sublimation due to the lack of a stable liquid phase for SiC. Despite its advantages, challenges such as micropipes, stacking faults, and dislocation densities persist.
Orbit & Skyline’s process engineering team optimizes growth techniques to maximize yield and reduce defects, ensuring superior wafer quality. By fine-tuning parameters such as temperature control and pressure regulation, we enhance SiC crystal production efficiency.
1.4 Physical Vapor Transport (PVT) Process
The PVT process involves melting high purity SiC powder in a growth chamber at temperatures exceeding 2000°C. The sublimated vapor then deposits onto a seed crystal, gradually forming a high-quality SiC boule. This method enables precise control over doping levels, essential for tailoring electrical characteristics. N-type doping (typically using nitrogen) enhances conductivity, while p-type doping (using aluminium) influences the polytype formation, affecting overall device performance.
2. From Boule to Epi-Ready Wafer
2.1 SiC Hardness and Processing Challenges
SiC is one of the hardest materials known, ranking 9–9.5 on the Mohs scale. This extreme hardness complicates the slicing and processing of SiC boules into wafers. Specialized grinding, lapping, and polishing techniques are required to achieve the precise dimensions necessary for semiconductor applications.
Orbit & Skyline’s Equipment Engineering services provide tailored solutions to overcome these challenges, ensuring precise wafer preparation for further processing.
2.2 Wafer Slicing and Surface Preparation
SiC boules undergo slicing using multi-wire saws coated with diamond slurry. This process must balance kerf loss (material waste) and throughput efficiency. Following slicing, wafers undergo lapping to ensure uniform thickness and surface quality, crucial for subsequent epitaxial growth.
2.3 Epi-Ready Polishing and Surface Finishing
To achieve EPI-ready surfaces, wafers undergo Chemical Mechanical Polishing (CMP), combining mechanical abrasion with chemical etching. Innovations in CMP technology, such as rapid thinning techniques, enhance material removal rates while maintaining surface integrity. This ensures defect-free epitaxial layers, which are critical for high-performance semiconductor applications.
3. Epitaxial Growth and Doping of SiC
3.1 High-Temperature Chemical Vapor Deposition (HT-CVD)
Epitaxial growth involves depositing thin, defect-free SiC layers on wafers to enhance electrical performance. HT-CVD is the industry standard, offering precise control over doping concentration and layer thickness. By using silicon and carbon precursors, diluted in hydrogen or argon carrier gases, HT-CVD facilitates uniform SiC layer growth.
3.2 Alternative Epitaxy Methods
Other epitaxy methods, such as Molecular Beam Epitaxy (MBE) and Liquid Phase Epitaxy (LPE), have been explored. However, challenges in impurity control, growth rate limitations, and scalability make HT-CVD the preferred approach for large-scale SiC production.
3.3 Scaling to 8” and 200mm Wafers
With the industry shifting towards 8” (200mm) SiC wafers, significant improvements in slicing and polishing processes have been made. Advanced wafer thinning and surface finishing techniques ensure high yield and minimal defect rates. The transition to larger wafers increases device yield per wafer while optimizing fabrication costs.
Conclusion
SiC wafer technology continues to evolve, with advances in boule growth, wafer slicing, and epitaxial deposition driving the transition from 6” to 8” wafers. The industry’s focus on improving material quality and reducing processing costs ensures that SiC remains a competitive alternative to silicon in high-power applications.
