  • Publication number: 20080047579
    Abstract: A method for determining the endpoint of a cleaning process in which a metallic residue is removed from an underlying surface which comprises a metal by contacting the residue with a cleaning agent which volatilizes the residue and which tends to attack the metal of the underlying surface and volatilizes it if the cleaning process is not terminated timely, and in which the metal comprising the underlying surface is more reactive with the cleaning agent than the metal of the metallic residue, the improvement which comprises terminating the cleaning process at a time when the ratio of the amount of volatilized metal to the amount of cleaning agent increases from a lower to a higher value.

  • Publication number: 20060254613
    Abstract: This invention relates to an improvement in the cleaning of contaminated tool parts having a coating of unwanted residue formed in a semiconductor deposition chamber. In this process, the contaminated parts to be cleaned are removed from the semiconductor deposition chamber and placed in a reaction chamber off-line from the semiconductor reactor deposition chamber, i.e. on off-line gas reaction chamber. The coating of residue on the contaminated parts is removed in an off-line reactor by contacting the contaminated parts with a reactive gas under conditions for converting the residue to a volatile species while in said off-line reactor and then removing the volatile species from said off-line gas reaction chamber.
