          Appeal No. 1997-3690                                                        
          Application 08/427,163                                                      


          wrenching fields and control of the hot carrier effect.                     
          However the Examiner has not shown that Tsang as disclosed                  
          already provides these characteristics.  Upon our review of                 
          Mizuno we fail to find that Mizuno teaches any benefits                     
          associated with forming the metal oxide layer in direct                     
          contact with the gate but rather Mizuno merely teaches that                 
          interposing a high dielectric material between the gate and a               
          silicone oxide spacer suppresses the gate wrenching field                   
          effects and gate capacity.  Mizuno does not teach or suggest                
          that the high dielectric material may be separated from the                 
          gate by thin oxide as in the metal oxide layer disclosed in                 
          Tsang.   Therefore, we fail to find that the Examiner has                   
          provided any evidence or suggestions of why the proposed                    
          modification would have been made by one of ordinary skill in               
          the art.                                                                    
               In view of the forgoing the decision of the Examiner                   
          rejecting claims 1, 3, 5 and 9 under 35 U.S.C. § 102 is                     
          affirmed; however, the decision of the Examiner rejecting                   
          claims 2, 4, 7, 8, 10 through 13, 15 and 16 is reversed.                    
               No time period for taking any subsequent action in                     
          connection with this appeal may be extended under 37 CFR                    
                                        -14-
