Shanghai Aishengna Starts Domestic Immersion DUV Production, Plans Five Units This Year

Shanghai Aishengna Electronic Technology Group, a state-owned enterprise, has begun producing domestic immersion deep ultraviolet (DUV) lithography machines. The company plans to manufacture about five units this year for delivery to SMIC, Hua Hong Semiconductor, and ChangXin Memory, with a target of around 20 units next year. The move comes as ASML is barred from exporting extreme ultraviolet (EUV) machines to China, making immersion DUV the most advanced available. Aishengna, founded in August 2023 with over 7 billion yuan in registered capital, is integrating teams from Chinese lithography startups. Insiders note the machines still require further testing and lag significantly behind ASML's models, posing no immediate commercial threat.

Changxin Technology Lists on A-Share Market on July 27, 2026, Marking China's Breakthrough in DRAM from Zero

Changxin Technology (Changxin Memory) began trading on the A-share market on July 27, 2026, representing a significant breakthrough in China's DRAM sector. The listing breaks the long-standing monopoly of Samsung, SK Hynix, and Micron in the memory chip market, achieving a from-zero-to-one breakthrough for domestic DRAM. The company's development has been supported by national semiconductor policies, market demand for self-controlled memory chips, entrepreneurial efforts, long-term investment from Hefei state-owned industrial funds, and surging demand from AI computing infrastructure. The IPO provides stable, long-term funding for R&D, production expansion, and product upgrades, helping to narrow the technology gap with global leaders and secure China's semiconductor supply chain. However, Changxin faces severe challenges including technology gaps in advanced lithography, yield rates, and patent portfolios, as well as market cyclicality and pricing power of incumbents.
