China’s quest for semiconductor self-sufficiency has reached a critical inflection point as the Chinese Academy of Sciences (CAS) unveils major breakthroughs in open-source architecture alongside stellar financial performances from the country’s leading foundries. At the recent Zhongguancun Forum, CAS launched the 'Xiangshan' open-source high-performance processor and the 'Ruyi' native operating system. This move signals a decisive shift toward RISC-V, an open-standard instruction set architecture that allows Chinese firms to bypass the patent royalties and geopolitical risks associated with Western-controlled ARM and x86 architectures.
The strategic importance of RISC-V cannot be overstated for Beijing’s long-term 'controllable computing power' roadmap. Described by experts as the 'universal standard' of the chip world, RISC-V offers a royalty-free foundation that Chinese state-backed institutions and private giants are now colonizing. The next-generation 'Kunming Lake' architecture has already entered joint development, supported by a formidable coalition including China Mobile, Alibaba, Tencent, and ByteDance. This vertically integrated ecosystem aims to cover the entire chain from hardware and operating systems to end-user applications.
On the commercial front, Semiconductor Manufacturing International Corporation (SMIC) reported a banner year for 2025, with net profits surging 36.3% to reach 5.04 billion RMB. This growth was propelled by a stabilizing smartphone market and a surge in AI-driven demand for consumer electronics. Most importantly, SMIC is reaping the rewards of 'localization conversion,' a trend where domestic designers increasingly move their wafer orders to Chinese foundries to mitigate supply chain vulnerabilities. This has solidified SMIC’s position as the world’s second-largest pure-play foundry.
Simultaneously, Hua Hong Semiconductor, China’s second-largest foundry, maintained a staggering capacity utilization rate of over 100% throughout 2025. While its net profit saw a marginal dip due to heavy investments in new capacity, its revenue grew by over 20%. The rapid ramp-up of its FAB9 facility, which hit a monthly capacity of 40,000 wafers by late 2025, underscores China’s aggressive expansion in mature and specialty nodes. These 'workhorse' chips remain essential for the automotive and industrial sectors, where China is rapidly building a dominant market share.
The broader market context remains complex, as reflected by the 4.79% drop in the Philadelphia Semiconductor Index. While global players grapple with high raw material costs and shifting AI capital expenditures, Chinese firms are finding a 'safe harbor' in domestic demand. Securities analysts suggest that as global giants like TSMC raise prices for advanced nodes and scale back mature 8-inch production, Chinese foundries are perfectly positioned to capture the resulting supply gap, further accelerating the localization of the global semiconductor supply chain.
