(2025 Revised Edition) Before starting the article, I would like to clarify that this represents my personal views, and the sources are from the internet. Please do not criticize if you disagree. Chapter 1: The Art of Sculpting in the Microscopic World In a late-night laboratory in Santa Clara, Silicon Valley, the blue plasma light reflects off the goggles of engineer James. He is debugging the latest EUV lithography machine, but the real “sculpting” drama is just beginning—the etching machine is about to make its entrance. This precision device, worth as much as a top-floor apartment in Manhattan, can carve circuits on silicon wafers that are 5000 times thinner than a human hair. By 2025, the global semiconductor equipment market has reached $38 billion, with etching equipment accounting for $28.15 billion, holding a 74% share, making it the undisputed “mother of processes.” The Awakening Moment of Domestic Etching Machines In 2018, engineers at Zhongwei Semiconductor Laboratory gathered around a silver-gray etching machine. When the selection on the screen exceeded 99.99%, Yin Zhiyao clenched his fist—this meant they could precisely remove the target material without damaging the silicon wafer. At this moment, there were only three months left until Applied Materials released its 5nm etching machine. Chapter 2: The Breakthrough Path of the Disruptor Rewind to 2004, when Yin Zhiyao returned to China with etching technology accumulated in the United States. At that time, the domestic etching market was monopolized by American and Japanese companies, with the price of an imported device reaching $30 million. Zhongwei’s first CCP etching machine had a yield of only 60%, while international giants had reached 99%. A turning point appeared in 2022. With the national big fund’s investment of 344 billion yuan in its third phase, Shanghai Microelectronics, in collaboration with the Chinese Academy of Sciences, overcame the technology for high-temperature ceramic components, extending the etching chamber’s lifespan from 3 months to 2 years. In 2024, Zhongwei’s 5nm etching machine officially entered TSMC’s supply chain, with a single unit priced at only one-fifth of ASML’s lithography machine. Chapter 3: The Starry Sea of Domestic Substitution In 2025, in Shanghai Lingang, the AccuraBE edge etching machine from Northern Huachuang is operating at full speed. This device can process the nano residues at the edges of 12-inch wafers, improving chip yield by 3 percentage points. At this moment, the proportion of domestic etching machines on the Yangtze Storage production line has reached 30%, while five years ago, this figure was less than 5%. Technology Breakthrough Map Aspect Ratio Revolution: The number of stacking layers for 3D NAND has exceeded 232 layers, with an etching aspect ratio of 80:1. Intelligent Evolution: AI algorithms optimize parameters in real-time, reducing the defect rate to 0.001 ppm. Material Innovation: Self-developed aluminum nitride ceramic components withstand temperatures of 1200°C. Chapter 4: The Future Battle: A Symphony of Atoms and Intelligence In the laboratory of Hengge Micro in Zhuhai, the world’s first wafer-level plasma multi-drive dissociation etching equipment is being debugged. This machine can simultaneously process 12-inch wafers, achieving atomic-level sculpting through quantum tunneling effects, paving new paths for 3D chip stacking. 2025-2034 Technology Roadmap Technical Fields: EUV-compatible etching; atomic layer etching; breakthroughs in intelligent manufacturing. Directions: EUV photoresist-specific etching solutions; single atomic layer precision control; AI-driven real-time process optimization. Domestic Progress: Zhongwei has completed laboratory validation; Northern Huachuang has entered the pilot stage; Huawei Cloud etching digital twin system. Conclusion: The Power of China on the Etching Knife As the global semiconductor industry races along the path of Moore’s Law, China’s etching craftsmen are redefining the rules of the game through independent innovation. From 5nm medium etching to wafer-level intelligent processing, from material breakthroughs to process innovations, this battle in the microscopic world is not only about technological sovereignty but also reflects the steadfast steps of a manufacturing powerhouse climbing towards the peaks of technology. As an engineer from Xinkailai stated at the 2025 Shanghai exhibition: “We are climbing the last ladder of semiconductor manufacturing, and every step must be taken with nanometer-level precision.” At this moment, the global market share of domestic etching equipment has reached 18%, and the story is far from over.
