半導體供應鏈消息：中國國産EUV已上線測試

中國國産EUV首先應用在DRAM廠商(長鑫)，用于制造10nm級制程的DDR5，預計三四個月後就能買到中國國産EUV制造的DDR5 DRAM了

















浙江大學極端光學技術與儀器全國重點實驗室已經向華為交付EUV物鏡裝調干涉儀

物鏡的精密裝配解決了，光源和雙工台解決了，基本上EUV核心技術算是全部突破了























中芯國際又在北京進行了産能擴張

這次是中芯京城2期項目，剛剛拿地

中芯在北京有好幾家合資公司，合資方各不相同

半導體設備終于不再是中芯國際産能擴張的障礙了

顫抖吧！用EUV製造的芯片即將產能過剩














中國對下一代晶片製造技術的研究是美國的兩倍多

2018年至2023年期間，全球共發表47.5萬篇跟晶片設計和製造有關的文章。其中，34%的作品由中國機構製作，美國和歐洲僅為15%、18%。被引用次數最高的前10%論文，中國貢獻比例高達50%，美國與歐洲則為22%和17%。


China doubles US research output on next-gen chips amid export bans — trade war fuels a research wave

The United States-China chip trade war is entering its fifth year, and it seems the U.S.'s intervention is coming back to bite it: A recent study by the Emerging Technology Observatory (ETO) found China has conducted more than double the United States' research on next-generation chipmaking technologies.

The ETO notes that 475,000 articles about chip design and fabrication were published between 2018 and 2023 worldwide. Of this body of work, 34% was produced by Chinese institutions, dwarfing the 15% coming from the United States and 18% from Europe. While chipmaking is not as popular for study as hot topics like AI and LLMs, China appears to be going all-in on studying the future of fabrication.

The quality of research coming from China is also at a high point. When looking only at articles in the top 10% of highest citations, 50% of this field comes from China. America and Europe sit far below at 22% and 17%, respectively. India, Japan, and South Korea also contribute to both metrics, but all fall well short of China's prolific research body and high citation count.
