The following information is excerpted from the USPTO (United States Patent and Trademak Office) document for patent number: 6,040,937

United States Patent: 6,040,937 was awarded to Miles on March 21, 2000.

    Method for fabricating a structure for a microelectromechanical systems (MEMS) device

    Abstract:
    An interferometric modulator (Imod) cavity has a reflector and an induced absorber. A direct view reflective flat panel display may include an array of the modulators. Adjacent spacers of different thicknesses are fabricated on a substrate by a lift-off technique used to pattern the spacers which are deposited separately, each deposition providing a different thickness of spacer. Or a patterned photoresist may be used to allow for an etching process to selectively etch back the thickness of a spacer which was deposited in a single deposition. A full-color static graphical image may be formed of combined patterns of interferometric modulator cavities. Each cavity includes a reflector, and an induced absorber, the induced absorber including a spacer having a thickness that defines a color associated with the cavity.
