Latest Patents

Karasawa holds a patent for a MEMS element and method of manufacturing the same. This patent describes a MEMS element that comprises a substrate with an opening, a vibrating membrane formed on the substrate through an insulating film, and a backplate fixed to a spacer on the substrate. The vibrating membrane features intermittent slits along its edge, while the backplate includes acoustic holes in the center and etching holes in the periphery, positioned closer to the edge side than the outermost peripheral end of the slits of the vibrating membrane in planar view. The design ensures that the edge of the vibrating membrane and the portion of the insulating film under the vibrating membrane are spaced apart from the bottom end of the spacer. The insulating film is etched from the edge of the vibrating membrane and the slits to under the vibrating membrane.
