At 3:30 p.m. on 12 June 2025, Dr Yuchen Wu of the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, delivered a compelling lecture entitled “Liquid-Bridge-Confined Micro-fabrication Techniques and Devices” in Room 362, Xueyuan 2, Yanqi Lake Campus. The event, hosted at the invitation of Professor Hui Huang as part of the “Frontiers in Materials Science and Engineering” lecture series, drew a large audience of faculty and students and fostered a vibrant academic atmosphere.
Dr Wu has long focused on liquid-phase micro-/nano-fabrication technologies and functional micro-/nano-devices. He has achieved a series of innovative results in interfacial confinement effects and liquid-bridge-confined assembly methods. To date, he has published 114 SCI-indexed papers in leading journals such as Nature Nanotechnology, Nature Electronics and Advanced Materials, garnering more than 10,000 citations, and has led over thirty projects funded by the National Natural Science Foundation of China and other agencies.
Opening his talk, Dr Wu reviewed global trends in advanced manufacturing and optoelectronic information technologies, highlighting the severe challenges traditional semiconductor micro-fabrication faces when integrating emerging nanomaterials. He then provided an in-depth explanation of the principles behind liquid-bridge-confined micro-fabrication, the pathways for constructing key devices and the prospects for applying the technique in high-performance optoelectronic device fabrication. By introducing concepts such as interfacial regulation and three-dimensional microscale topology control, he showcased his team’s original advances in three-dimensional flow manipulation and liquid-bridge evaporation templates, presenting new methods and solutions for highly integrated, high-precision micro-device manufacturing.
During the Q&A session, Dr Wu answered questions from the audience with patience and precision, sparking wide-ranging and in-depth academic discussions. Participants commented that the lecture broadened their research perspectives and provided valuable insights for future work in micro-/nano-fabrication and device integration.
