The microphone comprises: a substrate comprising an opening, a first electrode layer at the bottom of the opening, and at least one groove adjacent to the first electrode layer, with the groove and the opening on two opposing sides of a bottom surface of the first electrode layer; a separation material layer filling the groove; and a second electrode layer on the separation material layer, wherein the first electrode layer, the separation material layer, and the second electrode layer form a cavity. In this inventive concept, the separation material layer on the groove works as an anchor node embedding in the substrate to increases the effective contact area and the bonding power, and to improve the bonding quality between the second electrode layer and the substrate, which results in a strengthened second electrode layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Microphone and manufacture thereof","description":"A microphone and its manufacturing method, relating the semiconductor techniques, are presented.
