  • Ink jet prinithead
    Patent number: 11186089
    Abstract: Printheads and methods for forming printheads are described herein. In one example, a printhead includes a single resistor window in a conducting layer within the printhead. The printhead also includes a number of resistors formed in a resistor film deposited over the single resistor window. The resistors have two different widths, and each of the two different widths ejects a different droplet size when energized.
    Type: Grant
    Filed: September 19, 2019
    Date of Patent: November 30, 2021
    Assignee: Hewlett-Packard Development Company, L.P.

  • Material-saving resist spinner and process
    Patent number: 5449405
    Abstract: Spin coating of resist on a semiconductor wafer is done in a controlled chamber, starting with introducing a resist solvent vapor into the chamber from a nozzle or an adjacent chamber, applying the resist by spraying a very thin layer of the resist material and then removing solvent from the chamber. The result is a saving in resist material and enhanced coating uniformity.
