ABSTRACT:
A method of removing inorganic contamination from substantially the surface of a semiconductor substrate, the method comprising the steps of: reacting the inorganic contamination with at least one conversion agent, thereby converting the inorganic contamination; removing the converted inorganic contamination by subjecting it to at least one solvent agent, the solvent agent is included in a first supercritical fluid (preferably supercritical CO.sub.2); and wherein the converted inorganic contamination is more highly soluble in the solvent agent than the inorganic contamination.
