    Abstract: A microelectromechanical structure is formed by depositing sacrificial and structural material over a substrate to form a structural layer on a component electrically attached with the substrate (step 102). The galvanic potential of the structural layer is greater than the galvanic potential of the component. At least a portion of the structural material is covered with a protective material that has a galvanic potential less than or equal to the galvanic potential of the component (step 104 or 106). The sacrificial material is removed with a release solution (step 108 or 110). At least one of the protective material and release solution is surfactanated, the surfactant functionalizing a surface of the component.

    Abstract: A capacitive electromechanical transducer includes a substrate, a cavity formed by a vibrating membrane held above the substrate with a certain distance between the vibrating membrane and the substrate by supporting portions arranged on the substrate, a first electrode whose surface is exposed to the cavity, and a second electrode whose surface facing the cavity is covered with an insulating film, wherein the first electrode is provided on a surface of the substrate or a lower surface of the vibrating membrane and the second electrode is provided on a surface of the vibrating membrane or a surface of the substrate so as to face the first electrode. In this transducer, fine particles composed of an oxide film of a substance constituting the first electrode are arranged on the surface of the first electrode, and the diameter of the fine particles is 2 to 200 nm.
