          axis and the second axis, said work stage assembly having a work                   
          stage axis substantially parallel to the third axis, and the                       
          work stage assembly not being tiltable about the first axis or                     
          the second axis;                                                                   
                a first particle beam source for interacting with the                        
          workpiece, said particle beam source having a first particle                       
          beam source axis, the first particle beam source axis oriented                     
          at an acute angle greater than 0 degrees with the third axis;                      
          and                                                                                
                a second particle beam source for interacting with the                       
          workpiece, said second particle beam source having a second                        
          particle beam source axis oriented to form an acute angle                          
          greater than 0 degrees with the third axis, the particle beam                      
          sources being arranged such that one of the particle beam                          
          sources can be used to mill the workpiece and the other particle                   
          beam source can be used to image the workpiece.                                    

                Claims 21, 31, 38, and 41 stand rejected under 35 U.S.C                      
          § 103(a) as being obvious over Kaga.

          through 50 stand rejected under 35 U.S.C § 103 as being obvious                    
          over Kaga in view of Hattori and further in view of Hirose.                        
                Claims 26, 27, 37, 46, and 47 stand rejected under 35 U.S.C                  
          § 103 as being obvious over Kaga in view of Miyoshi.                               
                Claims 29, 30, 39, and 40 stand rejected under 35 U.S.C                      
          § 103(a) as being obvious over Kaga, Hattori, Hirose, and                          
          further in view of Miyoshi.
