  • MICRO-ELECTRO-MECHANICAL-SYSTEM (MEMS) MIRROR DEVICE HAVING LARGE ANGLE OUT OF PLANE MOTION USING SHAPED COMBED FINGER ACTUATORS AND METHOD FOR FABRICATING THE SAME
    Publication number: 20030090172
    Abstract: A micro-electro-mechanical-system (MEMS) mirror device includes a mirror component that is capable of moving upon electrostatic actuation. The MEMS mirror device also includes and one or more electrostatic actuators providing electrostatic actuation. The electrostatic actuators having plates disposed approximately perpendicular to the mirror component. The plates are disposed to define a gap between the plates that decreases along a direction perpendicular to a surface of the mirror component.

  • Micro-electro-mechanical-system (MEMS) mirror device and methods for fabricating the same
    Patent number: 6563106
    Abstract: A micro-electro-mechanical-system (MEMS) mirror device and methods for fabricating the same allow for a large range of angular motion for a center mirror component. The large range of angular motion for a center mirror component is dictated simply by a thickness of a substrate used or a thickness of a thick film used in making a support structure to support the center mirror component. The MEMS mirror device and methods for fabricating the same allow a large number mirror devices to be fabricated on a substrate. The MEMS mirror device includes a substrate. Electrodes are formed supported by the substrate. A support structure is formed adjacent to the electrodes. A hinge pattern and a mirror pattern having a center mirror component are formed such that the support structure supports the hinge pattern and mirror pattern.
