摘要： A boundary between a plasma and a plasma sheath is controlled such that a portion of the shape is not parallel to a plane defined by a front surface of the workpiece facing the plasma. Ions in the plasma are directed toward the workpiece. These ions can either seal pores or clean a material from a structure on the workpiece. This structure may, for example, have multiple sidewalls. A process that both cleans a material and seals pores in the structure may be performed.

摘要： A surface of an insulating workpiece is implanted to form either hydrophobic or hydrophilic implanted regions. A conductive coating is deposited on the workpiece. The coating may be a polymer in one instance. This coating preferentially forms either on the implanted regions if these implanted regions are hydrophilic or on the non-implanted regions if the implanted regions are hydrophobic.

摘要： A method of reducing surface roughness of a resist feature disposed on a substrate includes generating a plasma having a plasma sheath and ions therein. A shape of the boundary between the plasma and plasma sheath is modified using a plasma sheath modifier, so that a portion of the boundary facing the substrate is not parallel to a plane defined by the substrate. During a first exposure, the resist feature is exposed to electromagnetic radiation having a desired wavelength and the ions are accelerated across the boundary having the modified shape toward the resist features over an angular range.
