  • Patent number: 11378511
    Abstract: A method for detecting corrosion on a conductive object includes submerging a surface of the conductive object at least partially in an aqueous solution, flowing current through the surface of the conductive object by forming a voltage differential across the surface, varying the voltage differential across the surface while monitoring the current through the surface of the conductive object, determining a total charge corresponding to a corrosion level of the surface of the conductive object based on current versus voltage levels. The corrosion level may further be utilized in selecting a cleaning process to remediate the corrosion of the surface based on the corrosion level and in applying a protective corrosion barrier to on at least part of the surface after the cleaning process.

  • Publication number: 20100055920
    Abstract: The present invention discloses a new apparatus and method to enhance the plasma etch rate, etch selectivity and etch uniformity. The present invention will apply sonic waves to the work during plasma etch process. The sonic waves will enhance the plasma etch rate. The applied sonic waves can be of a mixture of multiple frequencies at the same time or at a different time. Applying different sonic frequency for etching different material will further amplify the etch selectivity. Sonic waves with multiple frequencies, especially with some lower frequency components, will further improve the etch uniformity over a large area.
