          Appeal No. 2001-2315                                                          
          Application 09/145,106                                                        

          claimed subject matter.  In re Fine, 87 F.2d 1071, 1074, 5 USPQ               
          1596, 1598 (Fed. Cir. 1988).  Only if this initial burden is met              
          does the burden of coming forward with evidence or argument shift             
          to the Appellants.  In re Oeticker, 977 F.2d at 1445, 24 USPQ at              
          1444.  See also Piasecki, 745 F.2d at 1472, 223 USPQ at 788.                  
               An obviousness analysis commences with a review and                      
          consideration of all the pertinent evidence and arguments.  “In               
          reviewing the [E]xaminer’s decision on appeal, the Board must                 
          necessarily weigh all the evidence and arguments.”  In re                     
          Oetiker, 977 F.2d at 1445, 24 USPQ2d at 1444.  “[T]he Board must              
          not only assure that the requisite findings are made, based on                
          evidence of record, but must also explain the reasoning by which              
          the findings are deemed to support the agency’s conclusion.”  In              
          re Lee, 277 F.3d 1338, 1344, 61 USPQ2d 1430, 1434 (Fed. Cir.                  
          2002).  With these principles in mind, we commence review of the              
          pertinent evidence and arguments of Appellants and Examiner.                  
               On a careful review, we find that the Examiner has failed to             
          provide the requisite findings in Biederman and Verzaro for                   
          suggesting to one of ordinary skill in the art to use a                       
          passivation layer comprising plasma polymerized methylsiloxane                
          extending over a portion of the die and the die carrier in a                  

                                           6
