    摘要: A method of treating resist features comprises positioning, in a process chamber, a substrate having a set of patterned resist features on a first side of the substrate and generating a plasma in the process chamber having a plasma sheath adjacent to the first side of the substrate. The method may further comprise modifying a shape of a boundary between the plasma and the plasma sheath with a plasma sheath modifier so that a portion of the shape of the boundary is not parallel to a plane defined by a front surface of the substrate facing the plasma, wherein ions from the plasma impinge on the patterned resist features over a wide angular range during a first exposure.

    摘要: An ion source includes an arc chamber having an extraction aperture, and a plasma sheath modulator positioned in the arc chamber. The plasma sheath modulator is configured to control a shape of a boundary between a plasma and a plasma sheath proximate the extraction aperture, wherein the plasma sheath modulator includes a semiconductor. A well focused ion beam having a high current density can be generated by the ion source. A high current density ion beam can improve the throughput of an associated process. The emittance of the ion beam can also be controlled.

    摘要: A plasma processing apparatus includes a process chamber, a platen for supporting a workpiece, a source configured to generate a plasma in the process chamber, and an insulating modifier. The insulating modifier has a gap, and a gap plane, where the gap plane is defined by portions of the insulating modifier closest to the sheath and proximate the gap. A gap angle is defined as the angle between the gap plane and a plane defined by the front surface of the workpiece. Additionally, a method of having ions strike a workpiece is disclosed, where the range of incident angles of the ions striking the workpiece includes a center angle and an angular distribution, and where the use of the insulating modifier creates a center angle that is not perpendicular to the workpiece.
