Aishengna: $1 Billion State-Backed Platform Takes Aim at ASML's DUV Integration Dominance
Miles Bennett
Shanghai state-owned newcomer Aisingna, registered with RMB 7 billion in capital, is coordinating China's first limited production of immersion DUV lithography tools — targeting about 5 systems by 2026 and marking the country's first platform-model challenge to ASML's DUV heartland.
Who is Aisingna and where does the money come from?
Aisingna (上海爱升纳电子科技集团) was established in Shanghai in August 2023 with RMB 7 billion (~$1.03 billion) in registered capital. Its legal representative is Ding Gongming.
Its two shareholders are Shanghai Electric Group and Shanghai Ruisaiweishang, a vehicle wholly owned by Shanghai International Trust. This means → the project carries dual endorsement from Shanghai's industrial and financial arms.
Ruisaiweishang was registered just five days before Aisingna — analysts believe it was created specifically as a financing vehicle for this lithography programme.
Does it build lithography tools? Why call it an "integration platform"?
Aisingna is not a conventional equipment start-up. It operates as a system-integration platform — linking capital, engineering talent, component suppliers and fab-level qualification.
In plain terms = SMEE (Shanghai Micro Electronics Equipment) supplies the core technology; Aisingna handles the last mile — turning lab-stage results into factory-ready machines.
The company has recruited staff from both SMEE and Shanghai Yuliangsheng Technology. Aisingna and Yuliangsheng are registered just hundreds of metres apart on Mindong Road in Pudong's Tangzhen semiconductor cluster, and records show they once shared an address. Yuliangsheng began testing a DUV prototype last year and has ties to SiCarrier, a Huawei-linked semiconductor equipment group.
How big is the production plan? How far behind ASML?
The project targets roughly 5 immersion DUV systems in 2026, rising to about 20 in 2027.
Immersion DUV lithography — injecting water between the projection lens and the wafer to print finer patterns than dry lithography — can reach more advanced nodes when paired with multi-patterning.
Key technologies include a 193 nm ArF light source, a high-NA projection optics system, dual wafer stages and immersion-fluid control. This means → the dual-stage architecture is the hallmark of ASML's TWINSCAN platform — one wafer is exposed while the other is measured and aligned, directly setting the throughput ceiling.
Early systems still show a significant gap versus ASML equivalents and require further testing.
Who would buy these tools?
First potential customers include SMIC, Hua Hong Semiconductor and CXMT — all leading Chinese fabs.
This reflects the project's commercial logic: not perfecting the product before finding buyers, but putting it into domestic supply chains first and iterating through real production.
What does this mean for the market?
After the reports emerged, global semiconductor-equipment stocks fell notably on fears that China may gradually reduce dependence on foreign lithography suppliers.
In plain terms = domestic DUV tools cannot replace ASML in the near term, but once this pathway proves viable, ASML's DUV business — not just EUV — faces long-term share erosion.
The real inflection point: whether domestic immersion DUV can deliver quantifiable yield and stability data in fab-level qualification.
