          Appeal No. 95-3936                                                          
          Application 08/135,324                                                      
                    comprising the steps of:                                          
                                                                                     
                    coating a wafer with a photoresist, said                          
                    photoresist producing a photoacid when irradiated                 
                    with radiation of a predetermined range of                        
                    wavelengths, said photoacid catalyzing a chemical                 
                    reaction when said photoresist is baked to increase               
                    the solubility of said photoresist in the irradiated              
                    areas with respect to the solubility of said                      
                    photoresist in the non irradiated areas;                          
                                                                                     
                    irradiating said photoresist on said wafer with                   
                    said radiation of a predetermined wavelength to                   
                    generate said photoacid defining a latent image in                
                    said photoresist on said wafer, said irradiating                  
                    step following said coating step;                                 
                                                                                     
                    preventing said photoacid from being                              
                    neutralized; and                                                  
                    baking said latent image in                                       
                    photoresist on said wafer, said baking step                       
                    following said preventing step.                                   
                    The examiner has not relied on any prior art to                   
          reject the appealed claims.                                                 
                    Claims 10 and 12 through 14 stand rejected under 35               
          U.S.C. § 112, first paragraph, on the grounds that the                      
          appealed claims are based on a disclosure which is only                     
          "enabling" for nitrogen or water as the agent which prevents                
          the photoacid from being neutralized.  We affirm.                           
                                       OPINION                                        
                    The question before us is whether appellants'                     
          disclosure would have enabled the hypothetical person of
