Shanghai Aishengna manufactures China’s first domestic immersion DUV wafer manufacturing tools ⚙️💻
📝 Brief summary
Shanghai Aishengna announced a major technological advance by launching the first domestically made Deep Ultraviolet (DUV) immersion wafer manufacturing tools in China. This achievement represents a strategic step in strengthening national production of semiconductor manufacturing equipment, and it aims to develop the first domestic scanner capable of producing chips using 7 nanometer (nm) technology by 2038. This development accelerates the reduction of dependence on foreign equipment and enhances competitiveness in the microprocessor manufacturing market.
🧠⚙️ Chip manufacturing technology and its importance in the semiconductor industry
The electronic chip industry requires extreme precision in manufacturing processes, which rely on advanced tools such as photolithography scanners to process silicon wafers.
In this process, Deep Ultraviolet light at a specific wavelength is used to draw highly precise patterns on the wafer surface. The immersion DUV technique refers to using a fluid (usually water) between the device lens and the silicon wafer to increase optical transfer precision, which is critical for achieving modern manufacturing technologies such as 7 nanometers.
☁️🔐 Why manufacturing immersion DUV tools is a strategic step for China?
So far, many Chinese companies have relied on imported photolithography equipment, especially from countries such as Japan and the Netherlands, particularly the Dutch company ASML, which specializes in ultra-precision lithography technologies. Supply stoppages due to geopolitical factors have created major constraints on China’s semiconductor industry development plans, making local development of manufacturing tools vital.
Advantages of manufacturing immersion DUV tools locally include:
- Reducing dependence on the supply of sensitive foreign equipment
- Improving control over the production and supply chain
- Enhancing the ability to develop chips to high manufacturing standards
- Supporting technical sovereignty and national security in the semiconductor sector
Shanghai Aishengna and its role in developing the local semiconductor industry 🧩
Shanghai Aishengna emerged as a pioneer in developing the first local photolithography tool with an immersion DUV system as part of China’s efforts to develop its semiconductor industry. Although the technology is still at an early stage compared with advanced countries, the company is working to build an integrated value chain that includes the design, manufacturing, and maintenance of these devices.
The company’s goal is to reach the manufacture of scanners that support 7 nanometer chips by 2038, an advanced technology that places China in a competitive position amid global shifts in the semiconductor market.

🔧⚙️ What are the technical challenges in manufacturing immersion DUV scanners?
Designing and manufacturing immersion DUV scanners requires extremely advanced engineering and technical precision. The main challenges are:
- Optical assembly precision to ensure DUV beams transfer without distortion
- Mechanical stability for nanometer-level positioning accuracy
- Controlling environmental contamination and liquid materials within the system
- Integration with production automation software and control systems to ensure wafer quality
- Precise and sustainable maintenance to preserve performance on production lines
Overcoming these obstacles requires major investments in research and development (R&D), attracting specialized engineers, and creating an integrated local manufacturing chain.
🧠💻 The impact of locally made 7 nanometer scanners on the processor industry
Manufacturing chips at 7 nanometer precision represents an important threshold in developing high-performance, energy-efficient chips, as it allows:
- Increasing transistor density on the wafer, which boosts speed and efficiency
- Reducing thermal power consumption, which supports the performance of computing devices and smartphones
- Supporting the launch of advanced processors and components for laptops, servers, and even artificial intelligence technologies
China’s acquisition of local manufacturing tools at this level means enabling its manufacturing companies to build chips that compete with global counterparts, which is vital amid restrictions on external technology.
“Local development of technical infrastructure is rarely achieved without long-term programs”
☁️💼 The role of 7 nanometer technology in the future of the digital economy
7 nanometer transistor manufacturing technology not only supports the CPU and GPU industries, but also affects several areas:
- Running advanced artificial intelligence (AI) applications
- Developing cloud computing applications and internet services infrastructure
- Accelerating Internet of Things (IoT) technologies thanks to improved energy efficiency
- Supporting cybersecurity systems based on reliable, lower-power hardware
Therefore, developing scanner tools that produce chips at this precision is essential to strengthening China’s position in the global technology arena.
🤔💡 What does this mean for users and local digital industries?
- Locally made smartphones and computers will become higher-performing based on improved chips
- Production lines will see greater supply chain stability thanks to reduced dependence on imports
- Chip-based industries such as smart cars and medical devices will expand with local technical support
- This achievement will help build a specialized education and training ecosystem in semiconductor engineering within China
“Investing in technology means a long-term investment in the future of industry”
🛤️ Technical takeaway: the road to semiconductor industry self-sufficiency in China
Developing the first local immersion DUV manufacturing tools represents an important element in China’s strategy to reduce its dependence on foreign technology and develop an integrated local industry for manufacturing microchips. Setting the goal of producing scanners that support 7 nanometer precision by 2038 points to ambitious national plans in manufacturing and technological innovation.
These steps are not merely a technological achievement; they also enhance China’s ability to compete in a pivotal global market built on digital technology, with a direct impact on all sectors of the modern economy, from smartphones and cloud computing to artificial intelligence applications.
“The future of the chip industry begins with advanced local manufacturing tools”
In this way, the achievement of Shanghai Aishengna forms a vital nucleus in China’s move toward broader technological self-reliance in the face of global challenges, paving the way for a comprehensive modernization of the computer and technology industry.
