          Appeal No. 2001-0929                                                        
          Application No. 08/697,321                                                  

          that other sources are used to create the plasma while a D.C.               
          voltage source is used to accelerate and implant the ions (Brief,           
          page 17; Shohet, col. 3, ll. 46-47; col. 6, ll. 14-16 and 37-42).           
               For the foregoing reasons and those stated in the Brief and            
          Reply Brief, we determine that the examiner has not established a           
          prima facie case of obviousness in view of the reference evidence.          
          Therefore we need not reach the issue of appellant’s evidence of            
          non-obviousness.  See Geiger, supra.  Accordingly, the examiner’s           
          rejection of claims 2-4 and 8-9 under 35 U.S.C. § 103(a) over               
          Nakayama in view of Chan and Kruger further in view of Shohet or            
          Yoshida is reversed.                                                        
               D.  Summary                                                            
               The rejection of claims 27-32 under 35 U.S.C. § 103(a) over            
          Gruen in view of Chan and Matossian is reversed.  The rejection of          
          claims 1, 5, 10 and 25-32 under 35 U.S.C. § 103(a) over Nakayama in         
          view of Chan and Kruger is reversed.  The rejection of claims 2-4           
          and 8-9 under 35 U.S.C. § 103(a) over Nakayama in view of Chan and          
          Kruger further in view of Shohet or Yoshida is reversed.                    





                                          9
