Shanghai Aishengna Electronic Technology Group has begun producing immersion deep-ultraviolet lithography systems designed to print circuit patterns onto silicon wafers. The state-backed Shanghai company is expected to deliver its first machines to SMIC, Hua Hong Semiconductor and ChangXin Memory Technologies in 2026, marking a notable step in China’s domestic semiconductor equipment push.
The systems are designed to support 28nm-class patterning in a single exposure and could reach more advanced nodes through multiple patterning. Initial production targets remain limited, at roughly five units in 2026 and 20 in 2027, while some critical components are still sourced internationally and local supplier delays have affected output.
For Chinese chipmakers, a domestic DUV supplier could reduce dependence on foreign lithography equipment and strengthen supply-chain resilience. However, long-term competitiveness will depend on whether the machines can match established systems in reliability, throughput, yield and service at high-volume production scale.

What's Driving This Trend
- Domestic Lithography Acceleration
- China’s push to commercialize homegrown DUV tools signals openings for localized semiconductor equipment ecosystems that reduce exposure to export controls.
- Resilient Chip Supply Chains
- Greater reliance on national suppliers reflects a shift toward semiconductor manufacturing networks built around redundancy, sovereignty and operational continuity.
- Multi-patterning Optimization
- Extending 28nm-class immersion DUV systems through multiple patterning creates room for software, process control and materials innovations that improve yield at advanced nodes.
Who This Affects Most
- Semiconductor Equipment
- Emerging domestic lithography platforms could reshape competitive dynamics in high-value wafer fabrication tools and create demand for supporting subsystems.
- Integrated Circuit Manufacturing
- Foundries and memory producers may gain strategic flexibility as alternative DUV capacity improves access to critical patterning infrastructure.
- Precision Components
- Localized production of optics, stages, light sources and metrology parts presents growth potential for suppliers able to meet high reliability standards.
