摘要： A plasma processing apparatus includes a process chamber, a platen positioned in the process chamber for supporting a workpiece, a source configured to generate a plasma in the process chamber having a plasma sheath adjacent to the front surface of the workpiece, and an insulating modifier. The insulting modifier is configured to control a shape of a boundary between the plasma and the plasma sheath so a portion of the shape of the boundary is not parallel to a plane defined by a front surface of the workpiece facing the plasma. Controlling the shape of the boundary between the plasma and the plasma sheath enables a large range of incident angles of particles striking the workpiece to be achieved.

摘要： An ion source includes an arc chamber having an extraction aperture, and a plasma sheath modulator. The plasma sheath modulator is configured to control a shape of a boundary between plasma and a plasma sheath proximate the extraction aperture. The plasma sheath modulator may include a pair of insulators positioned in the arc chamber and spaced apart by a gap positioned proximate the extraction aperture. 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 comprises a plasma source configured to produce a plasma in a plasma chamber, such that the plasma contains ions for implantation into a workpiece. The apparatus also includes a focusing plate arrangement having an aperture arrangement configured to modify a shape of a plasma sheath of the plasma proximate the focusing plate such that ions exiting an aperture of the aperture arrangement define focused ions. The apparatus further includes a processing chamber containing a workpiece spaced from the focusing plate such that a stationary implant region of the focused ions at the workpiece is substantially narrower that the aperture. The apparatus is configured to create a plurality of patterned areas in the workpiece by scanning the workpiece during ion implantation.
