                    Appeal No. 2004-0657                                                                                                                                  
                    Application No. 09/845,604                                                                                                                            


                    arguments concerning this rejection are in conflict with the well                                                                                     
                    established case law cited above and therefore are unconvincing.                                                                                      
                              As a consequence, we also hereby sustain the Examiner’s § 103                                                                               
                    rejection of claims 4 and 6 as being unpatentable over Muller.                                                                                        
                              We cannot sustain, however, the Examiner’s § 102 rejection of                                                                               
                    claims 7 and 10 or of the claims which depend therefrom.  Each of                                                                                     
                    claims 7 and 10 requires removing an upper portion of gate material                                                                                   
                    until the insulation cap of the stack or fin is exposed.  The                                                                                         
                    Examiner considers this claim requirement to be satisfied by                                                                                          
                    Muller’s disclosure at lines 35-42 in column 7 (e.g., see pages                                                                                       
                    15 and 19 of the answer).  However, this disclosure relates to                                                                                        
                    removing polysilicon layer 25 to thereby expose nitride layer 22                                                                                      
                    as shown in Figures 11A and 11B.  This nitride layer 22 does not                                                                                      
                    “read on” the insulation cap of the stack or fin which is exposed                                                                                     
                    during practice of the method defined by claims 7 and 10.  Indeed,                                                                                    
                    layer 22 is without question physically separated from patentee’s                                                                                     
                    fin (or stack) 4 as plainly revealed in the aforementioned Figures                                                                                    
                    11A and 11B.                                                                                                                                          
                              For this reason, we cannot sustain the Examiner’s § 102                                                                                     
                    rejection of claims 7–11, 13, 14 and 16 as being anticipated by                                                                                       
                    Muller.  Similarly, we also cannot sustain the Examiner’s § 103                                                                                       
                    rejection of claims 12 and 15 as being unpatentable over Muller                                                                                       

                                                                                    99
