China to triple domestic AI accelerator output with Huawei and SMIC

China is preparing a major scale-up of domestic Artificial Intelligence accelerator manufacturing to cut reliance on foreign computing, according to anonymous sources cited by the Financial Times. The plan reportedly dedicates an entire semiconductor fabrication facility to Huawei for production of its Ascend accelerators, with that plant scheduled to begin output by the end of the year. Two additional fabrication plants are expected to come online next year.

SMIC, China’s premier semiconductor manufacturer, has been supporting Huawei’s efforts, but the reporting indicates Huawei has moved to initiate its own independent production with SMIC’s assistance. Details on total wafer output and process node specifications for the dedicated fab were not stated. The expansion is presented as part of a broader push to significantly scale domestic manufacturing operations for accelerators used in Artificial Intelligence workloads.

Previous reporting cited in the article says Huawei, frustrated with limited SMIC capacity, has secured elements of the entire silicon production chain. That effort includes sourcing materials and chemicals, wafer fab equipment and chip-making equipment, and retaining chip design capabilities. A set of Huawei-backed companies forms the operation’s backbone: SiCarrier supplies optical and X-ray inspection tools, atomic force microscopes, alignment systems for metrology, gas-based and atomic layer deposition tools, plasma etchers, rapid thermal processors, and electrical testing platforms. SwaySure and Fujian Jinhua provide memory chips, Si´En and Pehgjin supply power chips, and PWX and PST handle logic.
