CLEANLINESS MONITOR AND A METHOD FOR MONITORING A CLEANLINESS OF A VACUUM CHAMBER

A cleanliness monitor for monitoring a cleanliness of a vacuum chamber. The cleanliness monitor may include a mass spectrometer, a molecule aggregation and release unit and an analyzer. The molecule aggregation and release unit is configured to (a) aggregate, during an aggregation period, organic molecules that are present in the vacuum chamber and (b) induce, during a release period, a release of a subset of the organic molecules towards the mass spectrometer. The mass spectrometer is configured to monitor an environment within the vacuum chamber and to generate detection signals indicative of a content of the environment; wherein a first subset of the detection signals is indicative of a presence of the subset of the organic molecules. The analyzer is configured to determine the cleanliness of the vacuum chamber based on the detection signals.

Etching apparatus and methods of cleaning thereof

A method for cleaning debris and contamination from an etching apparatus is provided. The etching apparatus includes a process chamber, a source of radio frequency power, an electrostatic chuck within the process chamber, a chuck electrode, and a source of DC power connected to the chuck electrode. The method of cleaning includes placing a substrate on a surface of the electrostatic chuck, applying a plasma to the substrate, thereby creating a positively charged surface on the surface of the substrate, applying a negative voltage or a radio frequency pulse to the electrode chuck, thereby making debris particles and/or contaminants from the surface of the electrostatic chuck negatively charged and causing them to attach to the positively charged surface of the substrate, and removing the substrate from the etching apparatus thereby removing the debris particles and/or contaminants from the etching apparatus.

System and method for residual gas analysis

The present disclosure provides embodiments of a system and method for detecting processing chamber condition. The embodiments include performing a wafer-less processing step in a processing chamber to determine the condition of the chamber walls. Based on an analysis of the residual gas resulting from the wafer-less processing step, an operator or a process controller can determine whether the chamber walls have deteriorated to such an extent as to be cleaned.

Detecting arcing using processing chamber data

A method and apparatus for detecting substrate arcing and breakage within a processing chamber is provided. A controller monitors chamber data, e.g., parameters such as RF signals, voltages, and other electrical parameters, during operation of the processing chamber, and analyzes the chamber data for abnormal spikes and trends. Using such data mining and analysis, the controller can detect broken substrates without relying on glass presence sensors on robots, but rather based on the chamber data.

Method and apparatus for revitalizing plasma processing tools

Methods for revitalizing components of a plasma processing apparatus that includes a sensor for detecting a thickness or roughness of a peeling weakness layer on a protective surface coating of a plasma processing tool and/or for detecting airborne contaminants generated by such peeling weakness layer. The method includes detecting detrimental amounts of peeling weakness layer buildup or airborne concentration of atoms or molecules from the peeling weakness layer, and initiating a revitalization process that bead beats the peeling weakness layer to remove it from the component while maintaining the integrity of the protective surface coating.
