    摘要: 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.
