  • Ink jet print head front face having a textured superoleophobic surface and methods for making the same
    Patent number: 8562110
    Abstract: An ink jet print head front face or nozzle plate having a textured superoleophobic surface that prevents undesirable drooling, wetting and/or adhesion of the ink on the print head. The textured surface includes a rim formed around the nozzle. Also described are methods for forming the textured superoleophobic ink jet print head front face or nozzle plate from silicon having the textured, oleophobic surface.

  • PROCESS FOR MAKING NANOCONE STRUCTURES AND USING THE STRUCTURES TO MANUFACTURE NANOSTRUCTURED GLASS
    Publication number: 20130025322
    Abstract: Fabrication method. At least first and second hardmasks are deposited on a substrate, the thickness and materials of the first and second hardmask selected to provided etch selectivity with respect to the substrate. A nanoscale pattern of photoresist is created on the first hardmask and the hardmask is etched through to create the nanoscale pattern on a second hardmask. The second hardmask is etched through to create the desired taper nanocone structures in the substrate. Reactive ion etching is preferred. A glass manufacturing process using a roller imprint module is also disclosed.
