    摘要: A power segmented electrode useful as part of an upper electrode and/or substrate support for supporting a substrate such as a semiconductor wafer in a plasma reaction chamber such as a single wafer etcher. The power segmented electrode includes a plurality of electrodes which are supplied radiofrequency power in a manner which provides uniform processing of the substrate. The power to the electrodes can be supplied through a circuit incorporating interelectrode gap capacitance, one or more variable capacitors, one or more current sensors, a power splitter, one or more DC biasing sources, and/or power amplifier.

    摘要: A cam-based arrangement configured to move a confinement ring along a first axis of a plasma processing chamber. The confinement ring is disposed in a plane that is orthogonal to the first axis. The cam-based arrangement includes a cam ring having a plurality of cam regions formed on a first surface of the cam ring. There is further included a plurality of cam followers in rolling contact with the first surface of the cam ring. There is also included a plurality of plungers oriented parallel to the first axis, each of the plurality of plungers being coupled to one of the plurality of cam followers and to the confinement ring, wherein the plurality of plungers move in an orchestrated manner parallel to the first axis as the cam ring is rotated and the plurality of cam followers stay in the rolling contact with the first surface of the cam ring.

    摘要: A focus ring assembly configured to substantially encircle a chuck of a plasma processing chamber. The focus ring assembly includes an annular dielectric body; and an electrically conductive shield surrounding the annular dielectric body. The electrically conductive shield is configured to be electrically grounded within the plasma processing chamber and includes a tube-shaped portion being disposed outside of the annular dielectric body and surrounding at least part of the annular dielectric body. The electrically conductive shield further includes an inwardly-protruding flange portion being in electrical contact with the tube-shaped portion. The flange portion forms a plane that intersects the tube-shaped portion. The flange portion is embedded within the annular dielectric body.

    摘要: A control circuit configured to control a reference voltage of a reference node of an electrostatic chuck power supply is disclosed. The electrostatic chuck power supply is configured to clamp a substrate to a bipolar electrostatic chuck. The electrostatic chuck has a first buried conductor and a second buried conductor. The electrostatic chuck power supply has a first output configured for being coupled with the first buried plate. The first output has a first output voltage referenced to the reference voltage of the reference node. The electrostatic chuck power supply also has a second output configured for being coupled with the second buried plate. The second output has a second output voltage referenced to the reference voltage of the reference node. The control circuit includes: a first resistor coupled in series with the first output; a first amplifier coupled to the first resistor for sensing a voltage drop across the first resistor; a second resistor in series with said second output; and a second amplifier coupled to the second resistor for sensing a voltage drop across the second resistor.

    摘要: The invention relates to an apparatus for lifting a substrate form a surface of a chuck subsequent to a processing step. The apparatus includes a perimeter pin for lifting the substrate from the surface of the chuck to a first position wherein the substrate is disposed on the perimeter pin during lifting. The perimeter pin is configured to overcome a holding force at an interface of the substrate and the surface. Generally, the holding force is generated between the substrate and the surface during the processing step. The apparatus further includes a center pin for moving the substrate from the first position to a second position wherein the substrate is disposed on the center pin during moving. The second position is further away from the surface of the chuck than the first position.
