Latest Patents

Yu-Hsiang Chiu holds a patent for an etching method for manufacturing MEMS devices. This method includes several steps: providing a substrate with a first surface and a second surface, where a base structure, a sacrificial structure, and at least one adhesion layer are arranged on the first surface. The adhesion layer is positioned between the base structure and the sacrificial structure, while the base structure is situated between the adhesion layer and the substrate. The process involves performing a surface grinding on the second surface, followed by a first plasma etching process using a mixed gas that includes oxygen and a nitrogen-based gas to remove the sacrificial structure. Finally, a second plasma etching process is conducted using a different mixed gas to eliminate the adhesion layer.
