  • Patent number: 7833358
    Abstract: A semiconductor processing chamber is cleaned by introducing a cleaning gas into a processing chamber, striking a plasma in a remote plasma source that is in communication with the processing chamber, measuring the impedance of the plasma, vaporizing a ruthenium containing deposit on a surface of the processing chamber to form a ruthenium containing gas mixture, and flowing the gas mixture through an analyzer and into an exhaust collection assembly. The measurement of the impedance of the plasma in combination with the ruthenium concentration provides an accurate indication of chamber cleanliness.

  • Patent number: 7826049
    Abstract: An inspection system can support operation in multiple states. For instance, when inspecting an article, such as a semiconductor wafer, the tool can switch between imaging multiple locations using respective detectors to another operating state wherein multiple detectors operating in multiple imaging modes inspect a single location. An inspection system may combine the use of multiple detectors for multiple locations and the use of multiple viewing angles or modes for the same locations and thereby achieve high throughput. The different imaging modes can comprise, for example, different collection angles, polarizations, different spectral bands, different attenuations, different focal positions relative to the wafer, and other different types of imaging.
