               Appeal No. 2003-1260                                                                        Page 9                
               Application No. 09/850,654                                                                                        


                      The sole claim within group 5 is claim 14.  Claim 14 is dependent on claim 13 and further                  
               requires that the spacer be in contact with the surface metallic material disposed in the via.                    
                      With regard to claim 14, Appellants argue that “the Examiner failed to cite a portion of                   
               [Kimizuka] that teaches or suggests a spacer being in contact with a metallic material disposed in                
               a via.” (Brief, p. 5).  Again, the film 13 of Kimizuka will inherently be in contact with the                     
               metallic material 8 within the via in locations where the conductive structure is offset from the                 
               via as inherently occurs in the device.                                                                           
                      We conclude that the Examiner has established a prima facie case of anticipation with                      
               respect to the subject matter of claim 14 which has not been sufficiently rebutted by Appellants.                 
                      Group 6                                                                                                    
                      Group 6 includes claims 16-20 and we have selected claim 16 as representative of the                       
               issues on appeal with regard to this group.  Claim 16 requires, among other things, “a conductive                 
               structure formed over the device layer in contact with, but not completely covering the metallic                  
               material disposed in the via, the conductive structure having at least one sidewall extending from                
               a surface of the metallic material.”  This limitation is similar to that discussed above with respect             
               to claim 13 and Appellants argued claims 13 and 16 together with respect to this limitation.  We                  
               sufficiently address the argument above in our discussion of Group 4.                                             
                      Claim 16 also requires that “the conductive structure and spacer on each of the at least                   
               one sidewall, enclose the metallic material in the via.”  Appellants further argue that “the                      
               Examiner failed to cite a portion of [Kimizuka] that teaches or suggests a conductive structure
