  • Holographic storage medium
    Patent number: 7122290
    Abstract: Holographic storage mediums, methods for producing the storage medium, methods for storing data in the holographic storage medium, and optical storage reading methods are described herein. The holographic storage medium can be formed from a composition comprising a thermally crosslinked polysiloxane binder; a photoactive material; and a photo-initiator, wherein the photoactive material has a concentration that remains about the same before and after a thermal cure process to form the thermally crosslinked polysiloxane binder.
    Type: Grant

  • Method for patterning devices
    Patent number: 6403392
    Abstract: A method of fabricating a device is provided. A shadow mask is positioned in a first position over a substrate. A first process is performed on the substrate through the shadow mask. After the first process is performed, the shadow mask is moved to a second position over the substrate, measured relative to the first position. After the shadow mask is moved to the second position, a second process is performed on the substrate through the shadow mask.

  • Method for patterning light emitting devices incorporating a movable mask
    Patent number: 6214631
    Abstract: A method of fabricatng a device is provided. A shadow mask is positioned in a first position over a substrate. A first process is performed on the substrate through the shadow mask. After the first process is performed, the shadow mask is moved to a second position over the substrate, measured relative to the first position. After the shadow mask is moved to the second position, a second process is performed on the substrate through the shadow mask.

  • Method of fabricating and patterning OLEDs
    Patent number: 6013538
    Abstract: A multiple layer patterning system with an undercut allows the deposition of a material onto a substrate from a direction substantially perpendicular to the substrate, followed by the angular deposition of a protective cap. Because of the angular deposition, the protective cap extends into the undercut and completely covers and surrounds any previously exposed surface of the material. The material is thereby protected from subsequent exposure to substances that may be deleterious.
