Abstract:
1. A method of workpiece processing comprising: implanting a part of a surface of a workpiece with a first ion species, wherein said workpiece is insulating; forming implanted regions on a surface of said workpiece using said first ion species, wherein said implanted regions are hydrophobic; depositing a coating on said surface of said workpiece after said implanting, wherein said coating is conductive; preferentially forming said coating on non-implanted regions adjacent said implanted regions on said surface whereby more of said coating is disposed on said non-implanted regions than on said implanted regions; and implanting said workpiece with a second ion species after said depositing, wherein said conductive coating forms a plasma sheath and said second ion species is focused by plasm sheath in regions of said surface located between said coating.
