  • Laser process for reliable and low-resistance electrical contacts
    Patent number: 7563707
    Abstract: Disclosed is a method for manufacturing an organic optoelectronic device. The method comprises providing a substrate, disposing a first electrode on the substrate, disposing a metal pad on the substrate, electrically separated from the first electrode, disposing a first material over the first electrode and at least partially over the metal pad, applying a beam, wherein the beam ablates the first material in an ablation window so that the ablation window includes at least a portion of an edge of the metal pad, and disposing a second electrode over the first material and over the ablation window so that the second electrode is in electrical contact with the at least a portion of an edge of the metal pad.
    Type: Grant
    Filed: October 7, 2008
    Date of Patent: July 21, 2009
    Assignee: Osram Opto Semiconductors GmbH
