A method for decoding auxiliary data from media signals in multimedia content decodes watermarks from different media signals and uses the watermarks to control processing of the multimedia content. A copy control method decodes a watermark from one of the media signals in multimedia content, and uses the watermark to control processing of the multimedia content. Another method uses a watermark decoded from a first media signal to decode a second media signal. Yet another method uses a watermark decoded from a media signal to decode metadata associated with the media signal. Finally, another method forms a key for decoding data from at least first and second watermarks extracted from first and second media signals.

Method of automatically controlling thickness of a metal film being deposited on a semiconductor wafer, the method comprising the steps of: producing an X-ray beam directed to the metal film during deposition of the metal film on the wafer in a deposition chamber, determining the thickness of the metal film based on detected X-ray fluorescence of the metal film, and comparing the determined thickness of the metal film with a preset value to continue the deposition of the metal film if the determined thickness is less than the preset value. 6. The method of claim 5, wherein the deposition of the metal film is stopped if the determined thickness reaches the preset value. 7. The method of claim 5, wherein the metal film is deposited using sputter deposition.
