  • Methods for Depositing, Releasing and Packaging Micro-Electromechanical Devices on Wafer Substrates
    Publication number: 20080096313
    Abstract: A projection system, a spatial light modulator, and a method for forming a MEMS device is disclosed. The spatial light modulator can have two substrates bonded together with one of the substrates comprising a micromirror array. The two substrates can be bonded at the wafer level after depositing a getter material and/or solid or liquid lubricant on one or both of the wafers. The wafers can be bonded together hermetically if desired, and the pressure between the two substrates can be below atmosphere.

  • Multi-mode projectors with spatial light modulators
    Publication number: 20060250583
    Abstract: Disclosed herein is a projection system that comprises an enhanced projection mode and regular mode. In the enhanced mode, media contents are displayed such that the perceived resolution is higher than the native resolution of the light valve. In the regular mode, media contents are projected with a resolution of the naïve resolution of the light valve. Viewers can operate the projection system in either of the two modes based upon the property of the media content or the viewers' preferences, or both.

  • Low cost hermetically sealed package
    Publication number: 20060220199
    Abstract: Disclosed herein is a device package that comprises a device having a top substrate that is disposed on a supporting surface of a package substrate. A package frame contacts the top surface of the top substrate and top surface of the package substrate, and hermetically seals the device between the top surfaces of the top substrate and package substrate. The device can be a semiconductor device, a microstructure such as a microelectromechanical device, or other devices.

  • Electrical connections in microelectromechanical devices
    Publication number: 20050250362
    Abstract: A micromirror device and a method of making the same are disclosed herein. The micromirror device comprises a mirror plate, hinge, and post each having an electrically conductive layer. One of the hinge, mirror plate, and post further comprises an electrically insulating layer. To enable the electrical connections between the conducting layers of the hinge, mirror plate, and post, the insulating layer is patterned.

  • Microelectromechanical devices with lubricants and getters formed thereon
    Publication number: 20050212067
    Abstract: The present invention provides a packaged microelectromechanical device having a plurality of deflectable elements formed on a substrate that has a getter and/or a lubricant disposed thereon. The substrate can be a glass substrate or a semiconductor wafer. The lubricant and/or getter can be disposed on the substrate or held by one or more containers that are attached to the substrate.
