    Abstract: 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.

The electrode assembly is arranged in the reactor chamber and includes at least one electrode having a lower surface that may have defined by at least one sacrificial protective plate (100). The electrode has a nonuniform thickness resulting from a plasma processing operation performed in the reactor chamber. The method includes a step of forming a plasma (120) designed to selectively etch the at least one electrode at the lower surface, followed by a step of etching the electrode with the aid of the plasma to reduce the nonuniformity in thickness (T(X,Z)) of the at least one electrode. The thickness of the electrode may be measured in situ using an acoustic transducer (210) during the processing of workpieces as well as during the restorative plasma etching of the electrode.

    Abstract: A method of and apparatus for providing tunable gas injection in a plasma processing system (10, 10′). The apparatus includes a gas injection manifold (50) having a pressurizable plenum (150) and an array of adjustable nozzle units (250), or an array of non-adjustable nozzles (502, 602), through which gas from the plenum can flow into the interior region (40) of a plasma reactor chamber (14) capable of containing a plasma (41). The adjustable nozzle units include a nozzle plug (160) arranged within a nozzle bore (166). A variety of different nozzle units are disclosed. The nozzle plugs are axially translatable to adjust the flow of gas therethrough. In one embodiment, the nozzle plugs are attached to a plug plate (154), which is displacable relative to an injection plate (124) via displacement actuators (170) connecting the two plates. The displacement actuators are controlled by a displacement actuator control unit (180), which is in electronic communication with a plasma processing system control unit (80). The gas flow into the chamber interior region is preferably controlled by monitoring the pressure in the plenum and in the chamber and adjusting the nozzle units accordingly. Where the nozzle units are not adjustable, a portion of the nozzles are sized to a first flow condition, and another portion of the nozzles are sized to a second flow condition.
