The back plate is coupled to the substrate and includes a dielectric layer and an electrode. The electrode is coupled to the dielectric layer and defines an opening that exposes a central portion of the dielectric layer. The diaphragm is oriented parallel to the back plate and is spaced apart from the back plate. In one implementation, a diameter of the opening is greater than or equal to 1/10 of the diameter of the diaphragm."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive microphone with shaped electrode","description":"A microelectromechanical systems (MEMS) die includes a substrate, a back plate, and a diaphragm.
