# Internet Technology [Chao words] # [looking at the footprints and steps of China's lithography machine technological progress from the president of ASML] ASML is the overlord of lithography machine, and its attitude towards China is like a chameleon, putting on a face-changing drama again and again-- 1. In 2002, Shanghai Microelectronics, which undertakes the country's major scientific research tasks, was founded. General Manager he Rongming took the technical team to Europe and the United States to study lithography technology. However, after arriving at ASML in the Netherlands, a German engineer was dismissive of the visit of the Chinese delegation, did not look at us at all, and directly put out the drawings of the lithography machine in front of us, and put down a harsh remark: "even if I give you a complete set of drawings, you will not be able to build a lithography machine!" It was not until 2016 that Shanghai Microelectronics finally achieved mass production of 90nm lithography machine. 2. After the United States began to impose sanctions on us in 2019, ASML became the main target of pressure from the United States, asking ASML to restrict the supply of Chinese lithography machines. Wen Ningke, president of ASML, repeated what he said that year: "even if I give you (China) drawings, you can't make them." The president thinks that China's lithography machines are too backward to catch up with them, so he is dismissive of China. 3. In January 2022, Wen Ningke, president of ASML, said: "it is impossible for China to master top lithography technology independently at present." The tone began to change this time. 4. In February 2023, Harbin University of Technology successfully developed an ultra-precision high-speed laser interferometer and won the Golden Flint Award of the World Photon Congress. This technology not only realizes high resolution and high precision displacement measurement at sub-nanometer level or even deep sub-nanometer level, but also can be successfully applied to the integrated development and performance testing of lithography machine prototypes from 350nm to 28nm process nodes in China. It provides a technical reserve for the research and development of EUV lithography machine. Wen Ningke, president of ASML, changed his face again, declaring: "US sanctions will force the Chinese to develop their own technology." The laws of physics in China are the same as those in the world, and there is no reason why China cannot build lithography machines. " Apparently he's starting to get anxious. 5. Harbin University of Technology successfully realized the DPP-EUV light source technology in April this year, which directly made ASML feel an unprecedented crisis. As a result, Wen Ningke, president of ASML, changed his face again, pointing the finger at the independent R & D behavior of Chinese enterprises. He said: "China is too obsessed with developing its own lithography machine and building its own industrial chain, which will directly destroy the global supply chain system!" He began to be afraid and hostile. I just want to swear once, fuck you! The best is yet to come. We'll see!
