Abstract
An integrated circuit structure comprises a conductor film that serves as a passive element or an interconnection, and a silicon substrate. A cavity is disposed between the substrate and the conductor film and thus underneath the conductor film. The substrate is formed by forming an island of oxide film in a surface of the substrate, and then wet etching the island from the surface of the substrate thereby forming the cavity.
