The semiconductor industry is strategic for great powers across the globe. It plays a pivotal role not only in technology but also in global politics. As nations vie for technological supremacy , their advancements in semiconductor technology directly influence their economic and military capabilities. A prime example of this is the ongoing tech warfare involving the United States and China, where the former has imposed sanctions aimed at halting the technical progress of its rival.
In light of these pressures, China has reacted decisively by investing heavily in its semiconductor industry to reduce reliance on foreign technologies. Two significant investments made in 2014 and 2019 sought to nurture its domestic chip manufacturing capabilities. In 2014, the Chinese government allocated approximately $19 billion to this sector, further escalating to $27.5 billion in 2019. But all these previous investments are dwarfed by the staggering $41 billion investment approved in late 2023, specifically aimed at enhancing lithography equipment manufacturing.
These efforts are starting to yield results. Recently, Pulin Technology, a burgeoning Chinese firm, delivered its first advanced photolithography machine using Nanoimprint Lithography (NIL) . This innovative machine is expected to produce 5nm chips , with future prospects of reaching 2nm technology levels. However, this is just the beginning, as China has ambitious plans in the pipeline for several other high-potential photolithography projects.
NIL Lithography and the Future of UVE Photolithography
NIL lithography, while promising, is distinct from the extreme ultraviolet (EUV) lithography employed by the Dutch company ASML. While NIL offers a more cost-effective solution, it involves multiple sequential processes, making it slower compared to EUV and UVP lithography. Thus, the Pulin machine represents just one step towards achieving a robust domestic semiconductor industry, and further advancements are anticipated as Chinese firms continue to innovate.
In March, reports emerged of a prototype of a UVE lithography machine developed entirely by Chinese engineers, showcased at Huawei’s research center in Dongguan, Guangdong Province . This machine is expected to rival ASML’s offerings, suggesting that by 2026 , China could possess the capability for large-scale production of advanced chips using UVE technology. The ambitions don’t stop here, though.
Greater resolution in practice implies that it is possible to produce semiconductors with more transistors, and, therefore, more sophisticated and powerful.
The Chinese Academy of Sciences is reportedly on the verge of completing what could be the most groundbreaking project launched in the Chinese semiconductor space. According to Dr. Kim , a specialist in integrated circuit manufacturing, China is approaching a “Deepseek” moment within the sector, poised to disrupt the chip market and compete head-to-head with the likes of the US, Taiwan, and South Korea.
However, the Chinese strategy for producing cutting-edge chips diverges from the methodologies established by its competitors. While ASML’s EUV machines have an integrated ultraviolet light source, plans from the Chinese Academy of Sciences indicate a pivot toward generating essential radiation for chip manufacturing using a synchrotron . This is a circular particle accelerator typically utilized in material analysis at the atomic level.
The synchrotron, known as HEPS (High Energy Photon Source) , is located in Beijing and is crucial for generating the ultraviolet light necessary for chip production. This technology’s advancement centrally addresses the critical task of transferring chip design patterns onto silicon wafers. Ultimately, this means producing integrated circuits with significantly enhanced resolution, allowing manufacturers to design chips with more transistors and greater capabilities.
At first glance, employing a particle accelerator may seem unrelated to semiconductor production, but HEPS has the capacity to generate high-power EUV light , making it an invaluable asset in the manufacturing process.
China’s strategy entails establishing several semiconductor manufacturing facilities around the synchrotron, which will supply the necessary EUV light , akin to how power plants deliver electricity to consumers. While the specific timeline for this ambitious semiconductor project remains undisclosed, its developments indicate that it will soon transition into production.
In conclusion, China’s aggressive investments in semiconductor technology not only signal its intent to become self-sufficient but also demonstrate its the potential to rival established leaders in the industry. As the nation accelerates its efforts in photolithography and other cutting-edge manufacturing processes, the global tech landscape may witness a significant shift, altering the dynamics of power and innovation in the semiconductor sector.
