  • Publication number: 20070097487
    Abstract: An optical deflection device for a display application. The optical deflection device includes a semiconductor substrate including an upper surface region and one or more electrode devices provided overlying the upper surface region. The optical deflection device also includes a hinge device including a silicon material and coupled to the upper surface region. The optical deflection device further includes a spacing defined between the upper surface region and the hinge device and a mirror structure including a post portion coupled to the hinge device and a mirror plate portion coupled to the post portion and overlying the hinge device.

  • Publication number: 20060121373
    Abstract: A method of manufacturing bonded substrate structures. The method includes providing a first substrate comprising a first surface region and processing the first surface region to form a first pattern region using a first photolithographic stepper characterized by a first tolerance criteria for alignment. The method also includes providing a second substrate comprising a second surface region and processing the second surface region through at least one masking process to form a second pattern region using a second photolithographic stepper characterized by a second tolerance criteria for alignment.

  • Patent number: 7042619
    Abstract: Hydrogen cleave silicon process for light modulating mirror structure using single crystal silicon as the base cross-member. Existing processes use two critical alignment steps that can contribute to higher actuation voltages and result in lower manufacturing yields. The hydrogen cleave process simplifies the manufacturing process to one step: transferring a thin film of single crystal silicon to the CMOS substrate, resulting in minimal alignment error and providing large bonding area.
