  • Process of forming a capacitative audio transducer
    Patent number: 7134179
    Abstract: A process of forming a capacitive audio transducer, preferably having an all-silicon monolithic construction that includes capacitive plates defined by doped single-crystal silicon layers. The capacitive plates are defined by etching the single-crystal silicon layers, and the capacitive gap therebetween is accurately established by wafer bonding, yielding a transducer that can be produced by high-volume manufacturing practices.
    Type: Grant
    Filed: December 13, 2004
    Date of Patent: November 14, 2006
    Assignee: Delphi Technologies, Inc.
    Inventors: John E. Freeman, William J. Baney, Timothy M. Betzner, Dan W. Chilcott, John C. Christenson, Timothy A. Vas, George M Queen, Stephen P Long
