The electrode regions may also be defined as electrode segments (420) separated by insulators (426). A set of process parameters A={n, τi, Φi, Pi, S; Li} is defined; wherein n is the number of RF feed lines connected to the electrode upper surface at locations Li, τi is the on-time of the RF power for the ith RF feed line, Φi is the phase of the ith RF feed line relative to a select one of the other RF feed lines, Pi is the RF power delivered to the electrode through the ith RF feed line at location Li, and S is the sequencing of RF power to the electrode through the RF feed lines. One or more of these parameters are adjusted so that operation of the plasma system results in a workpiece (176) being processed with a desired amount or degree of process uniformity.

摘要:
A method for monitoring consumption of a component, including the steps of emitting a radiation beam onto a first area of the component and detecting a portion of the radiation beam that is refracted by the component. A radiation level signal is generated based at least on a strength of the detected portion of the radiation beam, and a thickness of the component is determined based on the radiation level signal. The thickness of the component is compared to a predetermined thickness value, and a status signal is generated when the comparing step determines that the thickness of the component is substantially equal to or below the predetermined thickness value. When the comparing step determines that the thickness of the component is greater than the predetermined thickness value, the component is exposed to a process that can erode at least a portion of the component.

摘要:
A high-density plasma source (100) is disclosed. The source includes an annular insulating body (300) with an annular cavity (316) formed within. An inductor coil (340) serving as an antenna is arranged within the annular cavity and is operable to generate a first magnetic field within a plasma duct (60) interior region (72) and inductively couple to the plasma when the annular body is arranged to surround a portion of the plasma duct. A grounded conductive housing (400) surrounds the annular insulating body. An electrostatic shield (360) is arranged adjacent the inner surface of the insulating body and is grounded to the conductive housing. Upper and lower magnet rings (422 and 424) are preferably arranged adjacent the upper and lower surfaces of the annular insulating body outside of the conductive housing. A T-match network is in electrical communication with said inductor coil and is adapted to provide for efficient transfer of RF power from an RF power source to the plasma. At least one plasma source can be used to form a high-density plasma suitable for plasma processing of a workpiece residing in a plasma chamber in communication with the at least one source.
