Patent ID: 8840763

Claim:
A method, comprising: disposing a substrate onto a substrate support in a processing chamber, the processing chamber having a sputtering target disposed therein opposite the substrate support, the sputtering target comprising an element selected from the group consisting of zinc, cadmium, tin, indium, gallium, and combinations thereof; performing a first seasoning process while the substrate is disposed on the substrate support, the first seasoning process comprising: introducing an inert gas and a nitrogen containing gas into the processing chamber; and applying a first DC bias to the sputtering target to sputter material from the target; reducing the first DC bias to a second DC bias; and performing a first sputtering process comprising: introducing an oxygen containing gas along with the inert gas and nitrogen containing gas; increasing the second DC bias to a third DC bias to sputter material from the target; increasing the third DC bias to a fourth DC bias after supplying the oxygen containing gas for a predetermined time period during the first sputtering process; and depositing a first layer having a first composition on the substrate that comprises oxygen, nitrogen, and one or more elements selected from the group consisting of zinc, cadmium, tin, indium, gallium, and combinations thereof.
