Title: Innovations of Julius Ming-Lin Tsai
Introduction
Julius Ming-Lin Tsai is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of microstructure technology, holding two patents that showcase his innovative approach to selective etching methods and high-aspect-ratio microstructures.
Latest Patents
One of his latest patents is a selective etching method that includes a lateral protection function. The process involves several steps, starting with providing a substrate and forming a plurality of tunnels. A lateral strengthening structure is then created at the peripheral wall of the tunnels. The method continues with the removal of a bottom portion of the lateral strengthening structure and part of the substrate through an etching process, ultimately forming a lower structure and exposing an unstrengthened structure. The final step involves etching the unstrengthened structure laterally to create an upper structure.
Another significant patent is for a high-aspect-ratio microstructure (HARM). This structure consists of a substrate and a lower structure with a comb shape that is fixedly mounted on the substrate. The lower structure features first plural comb fingers, each with a thin slot. An upper structure with a comb shape contains second plural comb fingers, and there is a height difference between the lower and upper structures, resulting in an uneven surface. Additionally, a lateral strengthening structure is formed at the vertically peripheral walls of both the first and second plural comb fingers to protect them.
