          Appeal No. 1998-0038                                                        
          Application No. 08/236,780                                                  


               The appellants also seem to argue that Champetier                      
          contains no teaching or suggestion of a two-step process                    
          wherein contaminants are removed by reactive as well as non-                
          reactive plasmas pursuant to appealed independent claims 5 and              
          15.  This argument is unpersuasive.  As noted earlier and                   
          correctly pointed out by the examiner, Champetier expressly                 
          teaches removing contaminants by physical as well as chemical               
          action (e.g., again see lines 54-63 in column 5).
