Reports indicate that Shanghai Micro Electronics Equipment (SMEE) has finally started mass-producing its advanced immersion DUV lithography machine, the SSA800.
This is a significant milestone for China's semiconductor industry. For years, the global market for lithography tools—the complex machines that print circuits onto silicon wafers—has been dominated by a few companies, most notably ASML from the Netherlands. These machines are essential for manufacturing all modern chips, from those in your car to the ones in a data center.
So, what's driving this push? The primary catalyst has been the escalating tech rivalry between the U.S. and China. First, since late 2022, the U.S. and its allies, including the Netherlands, have tightened export controls, restricting China's access to advanced chipmaking equipment. This effectively cut off Chinese foundries from purchasing ASML’s latest DUV immersion tools, creating a major bottleneck.
In response, China has doubled down on its goal of self-sufficiency. Second, Beijing launched its third "Big Fund" in May 2024, a massive $47.5 billion investment vehicle specifically aimed at bolstering its domestic equipment and materials industry. This funding provided companies like SMEE with the capital needed to accelerate research, development, and production.
The new SMEE scanner is said to be capable of producing chips at the 28-nanometer node, a mature but widely used technology for applications in cars, IoT devices, and consumer electronics. While not cutting-edge compared to the 3nm or 5nm chips made with ASML's more advanced EUV machines, it represents a crucial step. It gives Chinese foundries like SMIC and Hua Hong a viable domestic alternative, insulating their mature-node capacity expansion from geopolitical pressures. This move could begin to chip away at ASML's lucrative DUV sales in China, which has historically been one of its largest markets. However, the impact is expected to be limited to the mature-node segment, as ASML still holds a monopoly on the EUV technology required for the most advanced chips.
In essence, SMEE's achievement is less about dethroning ASML overnight and more about building a resilient, self-reliant semiconductor ecosystem that can withstand external pressures. It’s a clear signal that China is determined to forge its own path in the global tech race.

- DUV Lithography: Deep Ultraviolet Lithography is a method used in semiconductor manufacturing to pattern circuits on a silicon wafer. Immersion DUV is an advanced version that uses a liquid medium to improve resolution, crucial for making chips at nodes like 28nm and below.
- Foundry: A semiconductor manufacturing plant that makes chips for other companies. Major examples include TSMC, Samsung, and China's SMIC.
- Export Controls: Government regulations that restrict the sale and transfer of specific technologies, goods, and services to foreign countries, often for national security reasons.
