             Appeal No. 2006-1663                                                                                
             Application No. 09/871,883                                                                          

             CLAIMS 23-24 AND 28-29                                                                              
                   Claim 23 recites the “liner-to-liner contact region further comprises second                  
             portions co-extensive with said lower conductive liner on portions of second sides                  
             of said lower level wire under vias of said second portion of said array of vias.”                  
             Claim 28 requires that the liner-to-liner contact region have “second portions co-                  
             extensive with said lower conductive liner on portions of second sides of said                      
             extensions of said lower level wire under vias of said second portion of said array                 
             of vias.”  Claim 24 requires the “liner-to-liner contact region further comprises a                 
             third portion co-extensive with said lower conductive liner on an end of said lower                 
             level wire under vias of said second portion of said array of vias.”  Claim 29 recites              
             that the liner-to-liner contact region has “a third portion co-extensive with said                  
             lower conductive liner on an end of said lower level wire under vias of said second                 
             portion of said array of vias.”                                                                     
                   The Examiner rejects claims 23-24 and 28-29 under 35 U.S.C. § 103(a) over                     
             Farrar in view of Havemann (Answer 4-6).                                                            
                   Appellants reiterate the following arguments they previously made with                        
             respect to claims 16-18: (1) Havemann does not disclose vias which are required                     
             by claims 23-24 and 28-29 and (2) Havemann’s encapsulation layer 48 (i.e., upper                    
             conductive liner) is disclosed as being made of silicon nitride which is non-                       
             conductive, so Havemann does not disclose an upper conductive liner.  These                         
             arguments are not persuasive.                                                                       
                   We addressed arguments (1) and (2) in our discussion of claims 16-18.  The                    
             same disposition (i.e., unpersuasive) of those arguments applies to claims 23-24                    
             and 28-29.                                                                                          


                                                       21
