  "account": "A Chinese start-up, Langdao Silex, showcased a prototype extreme ultraviolet (EUV) light-source machine at the China International Industry Fair in Shanghai. The company highlighted that 90% of the machine's components were locally sourced, with the majority developed in-house. The prototype is considered a significant step in transitioning EUV light sources from laboratory to industrial applications, although mass production is estimated to be three to five years away. An EUV light source is a critical component in advanced lithography equipment, generating the required extreme ultraviolet light to expose microscopic circuit patterns onto silicon wafers. This is the first public demonstration of China's progress in EUV technology, as the nation is currently barred from accessing the global supply chain for advanced chipmaking equipment due to US-led export restrictions. ASML, the world's sole manufacturer of EUV lithography systems, is prohibited from selling its machinery to Chinese customers. Despite the start-up's advancements, some industry experts remain doubtful about the prospects for rapid Chinese breakthroughs. ASML's CEO, Christophe Fouquet, expressed skepticism during an investor call, stating that Chinese customers have no incentive to develop domestic alternatives while they retain access to ASML's products. Langdao Silex was founded in 2024 and backed by state-backed and industry investors, including China Fortune-Tech Capital, an investment arm linked to China's leading chip foundry, Semiconductor Manufacturing International Corporation (SMIC). The start-up is part of a growing number of Chinese companies and research institutions making strides in advanced lithography development, although none has yet achieved commercial success. Other domestic equipment suppliers, such as Hwatsing Technology, Leadmicro, and Piotech, are also expanding their presence across various stages of the chipmaking process. China's localization efforts and reduced access to key components from Europe and Japan have led to an increasing adoption of domestically produced equipment, with domestic suppliers expected to capture 52% of the wafer-fabrication equipment market by 2028, up from 28% this year.",
  "summary": "A Chinese start-up has unveiled a prototype extreme ultraviolet (EUV) light-source machine – a component often described as the “heart” of advanced lithography systems – marking an early but critical step in Beijing’s drive for self-reliance in chipmaking equipment. At the China International Industry Fair in Shanghai, Langdao Silex displayed its self-developed EUV light-source system. Ninety per…",
