                                  DECISION ON APPEAL                                 
               This is a decision on appeal from the examiner's final                
          rejection of claims 8 through 13 and 19 through 24, which are all          
          of the claims pending in this application.                                 
               Appellant's invention relates to a method of forming an               
          EEPROM cell.  Claim 8 is illustrative of the claimed invention,            
          and it reads as follows:                                                   
               8. A method for making a floating gate in an EEPROM cell              
          construction process, comprising the steps of:                             
               (a) providing a semiconductor substrate of first                      
          conductivity type;                                                         
               (b) forming a first doped region of second conductivity type          
          in said semiconductor substrate having a first doping                      
          concentration to provide a tank at a surface of said substrate;
