  • Method for removing organic electroluminescent residues from a substrate
    Patent number: 7485580
    Abstract: A process for removing organic electroluminescent residues from a substrate is described herein. The process includes the steps of providing a process gas comprising a fluorine-containing gas, optionally an oxygen-containing gas, and optionally an additive gas; activating the process gas in a remote chamber using at least one energy source to provide reactive species; and contacting the surface of the substrate with the reactive species to volatilize and remove the organic electroluminescent residue from the surface.
