| 20080308411 | METHOD AND PROCESS FOR DEPOSITION OF TEXTURED ZINC OXIDE THIN FILMS - A method for sputtering a textured zinc oxide coating onto a substrate by reactive-environment hollow cathode sputtering comprises providing a sputter reactor that has a cathode channel and a flow exit end. The cathode channel allows a gas stream to flow therein. This cathode channel is at least partially defined by a channel-defining surface that includes at least one zinc-containing target. A gas is flowed through the channel, such that the gas emerges from the flow exit. A plasma is then generated such that material is sputtered off the channel-defining surface to form a gaseous mixture containing zinc atoms that is transported to the substrate. A reactive gas is then introduced into the sputter reactor so that the reactive gas reacts with the zinc-containing gaseous mixture to form the textured zinc oxide coating. | 12-18-2008 |
