          Appeal No. 94-3000                                                          
          Application 07/914,654                                                      


          used in said bath, and said organic solvent forming with said               
          liquid a mixture having a surface tension lower than that of                
          said liquid alone,                                                          
               wherein contaminants and drying marks are substantially                
          eliminated from said at least one substrate.                                
                                                                                     





               25.  A method of treating substrates comprising the steps              
          of                                                                          
               (a) immersing at least one substrate into a bath of a                  
          liquid,                                                                     
               (b) maintaining said at least one substrate in said bath               
          for a given time period,                                                    
               (c) withdrawing said at least one substrate from said                  
          bath at a speed such that substantially all of said liquid                  
          remains in said bath, and                                                   
               (d) directly contacting said at least one substrate with               
          a vapor of an organic solvent immediately upon leaving said                 
          bath, said vapor being free of condensation on said at least                
          one substrate upon withdrawing said at least one substrate                  
          from said bath, said organic solvent being chosen from a group              
          of organic solvents which are miscible with a liquid which is               
          the same as said liquid used in said bath, and said organic                 
          solvent forming with said liquid a mixture having a surface                 
          tension lower than that of said liquid alone,                               
               wherein contaminants and drying marks are substantially                
          eliminated from said at least one substrate by said step (d).               
               The references of record relied upon by the examiner are:              
                                          3
