  • Hydrogenation of polysilicon thin film transistors
    Patent number: 6057182
    Abstract: A method of making a liquid crystal display which has a layer of polysilicon on a surface of a substrate, a gate of a conductive material over and insulated from a portion of the polysilicon layer, a layer of an insulating material over the gate, and a metal layer on the insulating layer. The method includes forming a layer of an insulating material over the metal layer and then subjecting the device to a plasma containing hydrogen to diffuse the hydrogen through the insulating layers and the metal layer into the polysilicon layer.
