Highlight - Breaking the "Bottleneck" with Scanning Electron Microscopes to Break Foreign Monopoly

The "Field Emission Gun Scanning Electron Microscope" displayed in the "Innovation and Entrepreneurship Creating New Momentum for High-Precision Development" exhibition area is a project result that truly addresses the "bottleneck" problem.

The scanning electron microscope is an essential instrument for high-end scientific research, widely used in various research fields and industrial manufacturing, and is recognized as one of the 35 "bottleneck" issues. High-end scanning electron microscopes have long been monopolized by the US, Germany, Japan, and the Czech Republic, with domestic scanning electron microscopes having a maximum resolution of only 3 nanometers. However, the first field emission gun scanning electron microscope developed by the Chinese Academy of Sciences has a resolution of less than 1 nanometer, reaching international first-class technical standards, and possesses completely independent intellectual property rights, breaking the foreign technology monopoly and filling the domestic gap, providing important support for China's frontier scientific research and the independent controllability of high-end equipment in strategic emerging industries.

The research and development cycle of high-end scientific instruments is long, with high technical barriers, requiring substantial continuous financial investment, professional technical talent, and supporting upstream industrial chains. During the development and industrialization of the field emission gun electron microscope, many technical and engineering challenges were encountered. As a well-established scientific instrument research and development unit with over sixty years of history, the Chinese Academy of Sciences has overcome multiple key technologies in this process and has mastered the complete production and manufacturing process of the field emission gun scanning electron microscope. The two models it has launched have already achieved mass sales in fields such as life sciences, semiconductor testing, and new energy materials.
