Latest Patents

Yamamoto holds a patent for an innovative etching method. This method involves etching a substrate by plasma through a mask with a predetermined pattern located at the back of a silicon layer of the substrate. The process includes a main etching step where plasma is generated by supplying a process gas that consists of a mixed gas with a specific flow ratio of fluorine compound gas, oxygen gas, and silicon fluoride gas. The substrate is then etched by the plasma, followed by an over etching step that further etches the substrate while applying a high frequency for bias.
