For years, the race to build faster and more efficient computer chips has been tied to a single piece of equipment called the extreme ultraviolet (EUV) lithography machine.
This highly complex system is considered essential for manufacturing the most advanced silicon chips.
China has largely been cut off from this technology by export restrictions, creating a major obstacle for its semiconductor ambitions.
Now, a Shanghai start-up called Yuanjiwei is betting that the future of computing may not require EUV machines at all.
The company has unveiled what it describes as the world’s first 8-inch pilot production line dedicated to two-dimensional (2D) semiconductors , a technology that could eventually allow advanced chips to be built using entirely different materials and manufacturing methods.
The chip industry is stuck in a silicon loop
The announcement is significant because the semiconductor industry is running into a fundamental problem.
For decades, chipmakers improved performance by shrinking transistors —the tiny switches that process information.
However, as these components approach atomic dimensions, they become increasingly difficult and expensive to manufacture.
They also suffer from unwanted electrical leakage, where current continues flowing even when a transistor is supposed to be off.
This leakage wastes energy and generates heat.
Researchers around the world have been exploring alternatives to conventional silicon, and 2D materials have emerged as one of the most promising candidates.
Two-dimensional semiconductors are made from materials only one or a few atoms thick.
Unlike conventional silicon, which forms a three-dimensional crystal structure, electrons in 2D materials move primarily within an ultra-thin layer, giving them their “two-dimensional” name.
Due to this unique structure, 2D transistors can maintain strong electrical performance even at extremely small scales, where conventional silicon devices become increasingly difficult to control.
“Compared with conventional silicon-based chips, 2D semiconductors offer several potential advantages.
Due to the atomic-scale thickness of 2D materials, transistors in 2D semiconductors could be made smaller without relying on increasingly complex transistor structures,” Bao Wenzhong, chairman of Yuanjiwei, told SCMP .
Another advantage could emerge when 2D semiconductors are combined with 3D chip stacking technologies.
Since the materials are extremely thin, multiple layers of electronic circuits could potentially be stacked more efficiently, increasing computing power and memory density without dramatically increasing a chip’s footprint.
However, researchers have studied such materials for more than a decade, but scaling them from laboratory samples to wafer-level manufacturing has proven extraordinarily difficult.
This is one of the reasons the chip industry has remained heavily dependent on silicon transistors.
From the lab bench to the factory floor
The researchers at Yuanjiwei did not invent a new material but created an industrial process capable of turning laboratory research into actual chips.
According to the company, its new pilot line covers the entire manufacturing chain, from preparing 2D semiconductor materials to integrating them into finished devices.
It also supports tape-out, the final stage of chip design before production.
This development addresses one of the biggest hurdles in 2D semiconductor research , which is proving that these atom-thin materials can be manufactured consistently at a scale relevant for the chip industry.
Previous studies have shown that 2D materials can be used to build high-performance electronic devices, and researchers have recently demonstrated wafer-scale approaches for growing and fabricating these ultra-thin materials.
However, these efforts largely focused on proving that the technology works rather than on creating a fully working production pipeline.
Turning laboratory demonstrations into a repeatable manufacturing process requires solving additional challenges, including material preparation, device fabrication, and chip integration.
Yuanjiwei says its new 8-inch pilot line is designed to bridge that gap by bringing multiple stages of chip production together on a single platform.
The company further aims to use this manufacturing base to develop advanced processes, eventually reaching a 5-nanometer-equivalent chip technology by 2029 without relying on EUV lithography.
These efforts fit into a broader push by China to find alternative routes to advanced semiconductor manufacturing.
Facing US-led restrictions on access to some of the world’s most advanced chipmaking tools, the country has invested heavily in chip research.
They are bringing together universities, state-backed laboratories, equipment makers, and semiconductor firms to reduce dependence on foreign technologies.
“The aim is for China to eventually be able to make advanced chips on machines that are entirely China-made,” an anonymous source with direct knowledge of the secret EUV project told Reuters .
A promising route, but many obstacles remain
Despite the excitement surrounding 2D semiconductors , experts caution that commercial success is far from guaranteed.
Manufacturing chips is one of the world’s most complex industrial processes.
Industry specialists attending Yuanjiwei’s unveiling reportedly stressed that no single company can commercialize 2D semiconductors on its own because every part of the supply chain must mature together.
There are also technical questions that remain unanswered.
While researchers have repeatedly demonstrated high-performance 2D transistors in laboratories, producing millions or billions of identical devices with high reliability remains a major challenge.
Many promising semiconductor technologies have struggled to make the leap from research papers to mass production.
Still, the launch of the pilot line marks an important transition.
Rather than simply publishing laboratory results, Yuanjiwei is attempting to prove that 2D semiconductors can be manufactured at an industrial scale.
If the company succeeds, it could provide China with a path toward advanced chips that bypasses one of the most heavily restricted technologies in the semiconductor world.
