Abstract:
A method of cleaning metal-containing deposits from a metal surface of a process chamber component includes immersing the metal surface in an electrochemical cleaning bath solution. A negative electrical bias is applied to the metal surface to electrochemically clean the metal-containing deposits from the metal surface. The cleaning method is capable of removing metal-containing deposits such as tantalum-containing deposits from the metal surface substantially without eroding the surface, and may be especially advantageous in the cleaning of components having textured surfaces.
