          Application No. 10/135,005                                                         

          II.  The 35 U.S.C § 103 rejection of claims 21, 31, 38, and 41                     
                as being obvious over Kaga                                                   
                The examiner’s position for this rejection is set forth on                   
          pages 3 through 7 of the final office action mailed April 12,                      
          2004.  We particularly refer to the paragraph bridging pages 6                     
          through 7 of this final office action.  In this paragraph, the                     
          examiner concludes that it would have been obvious to have                         
          inclined Kaga’s first/second particle beam source axis oriented                    
          at an acute angle that is greater than 0 degrees, resulting in                     
          an acute angle between the first/second beam source axis and the                   
          first and second axis.  The examiner states that motivation to                     
          do so is “to impart an ion beam at an acute angle, greater than                    
          0˚, to the substrate.”  The examiner states further that it                        
          would have been obvious to optimize operation of the claimed                       
          invention.  Final Office Action, page 7.                                           
                On page 5 of the Brief, appellants state that in the                         
          Advisory Action, the examiner stated that it would be completely                   
          obvious “to change Kaga’s relative angle theta by changing the                     
          position of either Kaga’s first and/or second particle beam                        
          sources.  Further, it is appreciated that because Kaga’s stage 2
