Methods for removing contamination from surfaces in substrate processing systems

Methods for removing contamination from a surface disposed in a substrate processing system are provided herein. In some embodiments, a method for removing contaminants from a surface includes: providing a first process gas comprising a chlorine containing gas, a hydrogen containing gas, and an inert gas to a process chamber having the surface disposed within the process chamber; igniting the first process gas to form a plasma from the first process gas; and exposing the surface to the plasma to remove contaminants from the surface. In some embodiments, the surface is an exposed surface of a process chamber component. In some embodiments, the surface is a surface of a first layer disposed atop a substrate, such as a semiconductor wafer.

Method for controlling aluminum dissolution

A process for controlling the dissolution of a metal in an acid bath is described. The metal may comprise aluminum and the acid bath may contain a metal catalyst that causes the metal to dissolve. In order to control the rate of dissolution, the metal can be contacted with a cathodic member. In one embodiment, the process can be completely stopped even without removing the metal from the acid bath. The cathodic member provides anodic protection to the metal. In one embodiment, the cathodic member is made from a nickel-chromium-based alloy.
