  • Patent number: 8530259
    Abstract: A method for fabricating a micro electromechanical device includes providing a first substrate including control circuitry. The first substrate has a top surface and a bottom surface. The method also includes forming an insulating layer on the top surface of the first substrate, removing a first portion of the insulating layer so as to form a plurality of standoff structures, and bonding a second substrate to the first substrate. The method further includes thinning the second substrate to a predetermined thickness and forming a plurality of trenches in the second substrate. Each of the plurality of trenches extends to the top surface of the first substrate. Moreover, the method includes filling at least a portion of each of the plurality of trenches with a conductive material, forming the micro electromechanical device in the second substrate, and bonding a third substrate to the second substrate.

  • Patent number: 8424343
    Abstract: Light-absorbing glass frit material is used to seal an opening in a device or a plurality of devices in a batch process. The glass frit material is applied and then irradiated with light having a wavelength absorbed by the glass frit material so that the glass frit ball undergoes a glassy transition and forms a seal. When sealing an opening in a device, the glass frit material may be applied as a spherical ball such that the spherical ball covers the opening. The volume of the spherical ball may be selected to determine the final shape of the seal.

  • Patent number: 8361331
    Abstract: A MEMS mirror for a laser printing application includes providing a CMOS substrate including a pair of electrodes, and providing a reflecting mirror moveable over the substrate and the electrodes. Voltages applied to the electrodes create an electrostatic force causing an end of the mirror to be attracted to the substrate. A precise position of the mirror can be detected and controlled by sensing a change in capacitance between the mirror ends and the underlying electrodes.
