摘要:
A plasma-processing chamber including pulsed gas injection orifices/nozzles utilized in combination with continuous flow shower head injection orifices is described. The continuous flow shower head injection orifices introduce a continuous flow of gas while the pulsed gas injection orifices/nozzles cyclically inject a high-pressure gas into the chamber. In one embodiment, a central computer may monitor and control pressure measurement devices and utilize the measurements to adjust processing parameters (e.g. pulse duration, pulse repetition rate, and the pulse mass flow rate of processing gases).

A wall film monitoring system includes first and second microwave mirrors in a plasma processing chamber each having a concave surface. The concave surface of the second mirror is oriented opposite the concave surface of the first mirror. A power source is coupled to the first mirror and configured to produce a microwave signal. A detector is coupled to at least one of the first mirror and the second mirror and configured to measure a vacuum resonance voltage of the microwave signal. A control system is connected to the detector that compares a first measured voltage and a second measured voltage and determines whether the second voltage exceeds a threshold value. A method of monitoring wall film in a plasma chamber includes loading a wafer in the chamber, setting a frequency of a microwave signal output to a resonance frequency, and measuring a first vacuum resonance voltage of the microwave signal. The method includes processing the wafer, measuring a second vacuum resonance voltage of the microwave signal, and determining whether the second measured voltage exceeds a threshold value using the first measured voltage as a reference value.

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.
