Group 1: Photolithography Machines - The photolithography machine is a critical device in semiconductor manufacturing, with the process being complex and costly, comprising steps like coating, exposure, and development [18][19]. - The global photolithography machine market is estimated to exceed $30 billion, with ASML dominating the market, holding an 82.1% share in 2022 [39][45]. - The demand for domestic photolithography machines is rising due to the expansion of wafer fabrication plants in China, with expected monthly capacity growth from 2.17 million wafers in 2023 to over 4.14 million by the end of 2026 [15][50]. Group 2: Technological Developments - The SSA600/20 series is currently the most advanced domestic photolithography machine, capable of mass production with a resolution of 90nm, primarily used for mature processes [3]. - SMEE is focusing on developing a 28nm immersion photolithography machine, with the goal of delivering the first unit by 2024-2025, although actual progress may vary [4]. - The resolution of photolithography machines can be enhanced through shorter wavelengths and increased numerical apertures, with ASML's EUV machines achieving resolutions as low as 8nm [11][33]. Group 3: Market Dynamics - The photolithography machine market is characterized by a few dominant players, with ASML, Canon, and Nikon controlling the majority of the market share [45]. - The U.S. has intensified export controls on semiconductor technology to China, making the localization of photolithography machines a pressing issue for the Chinese semiconductor industry [50][65]. - The construction of new wafer fabs and the rapid development of AI technologies are driving the demand for advanced photolithography machines in China, which are crucial for producing smaller transistors and higher performance chips [52][59]. Group 4: Investment Recommendations - The article suggests focusing on the domestic photolithography machine supply chain, highlighting companies such as Maolai Optical, Fuguang Co., Huicheng Vacuum, Inno Laser, Sudavige, and Chip Quasar as potential beneficiaries of this trend [96].
