  • Patent number: 7408250
    Abstract: A microstructure is packaged with a device substrate of the microstructure being attached to a package substrate. For dissipating possible deformation of the microstructure, which may result in device failure or quality degradation of the microstructure, an adhesive material comprising a compliant adhesive component is applied and positioned between the device substrate and package substrate.

  • Patent number: 7295363
    Abstract: Disclosed herein is method of operating a device that comprises an array of micromirrors. The method comprises a process usable for repairing stuck micromirrors of the micromirror array during the operation. The reparation process applies, at the ON state, two consecutive refresh voltages to the mirror plates of the micromirrors in the array with the pulses being separated in time longer than the characteristic oscillation time of the micromirrors. The reparation process can be applied independently to the micromirrors. Alternatively, the reparation process can be incorporated with a bias inversion process.

  • Publication number: 20070062647
    Abstract: An isolative substrate edge area processing method and apparatus is described. The apparatus has an isolator for isolating and processing by dry chemical technique a portion of a substrate including a substrate edge region. The isolator has nozzles for directing a flow of reactive species towards the edge area of the substrate and a purge plenum for biasing flow of reactive species towards an exhaust plenum while the substrate rotates on a chuck. Tuned flow control prevents migration of reactive species and reaction byproducts out of the processing area. A method for processing a substrate with the isolator involves directing a flow of reactive species at an angle towards an edge area of the substrate while forming a boundary around the processing area with flow control provided by the purge plenum, and exhaust plenum.
