    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 tool is used to deposit material on a workpiece. For example, a method for conformal deposition of material is disclosed. In this embodiment, the plasma sheath shape is modified to allow material to impact the workpiece at a range of incident angles. By varying this range of incident angles over time, a variety of different features can be deposited onto. In another embodiment, a plasma processing tool is used to etch a workpiece. In this embodiment, the plasma sheath shape is altered to allow ions to impact the workpiece at a range of incident angles. By varying this range of incident angles over time, a variety of differently shaped features can be created.

    摘要: A method of plasma doping includes generating a plasma comprising dopant ions proximate to a platen supporting a substrate in a plasma chamber. The platen is biased with a bias voltage waveform having a negative potential that attracts ions in the plasma to the substrate for plasma doping. At least one sensor measuring data related to charging conditions favorable for forming an electrical discharge is monitored. At least one plasma process parameter is modified in response to the measured data, thereby reducing a probability of forming an electrical discharge.
