          Appeal No. 96-1584                                                          
          Application 08/066,697                                                      


          neither reference alone discloses the claimed structure.  Results           
          obtained from appellant's specific construction appear to be                
          nothing more than those which would have been expected by the               
          artisan.  Expected results are evidence of obviousness.  In re              
          Skoner, 517 F.2d 947, 950, 186 USPQ 80, 82 (CCPA 1975).                     
               The fact that Muramatsu does not state that voltage on its             
          trench material 20 during device operation is insufficient to               
          cause the avalanche-generation in question is not deemed                    
          controlling here.  There is no disclosure in Muramatsu that its             
          apparatus suffers from such degradation nor has appellant                   
          submitted any evidence to establish that as a fact.  Appellant              
          acknowledges at page 3, lines 16-22, of its specification that              
          avalanche-generation of electron/hole pairs occurs only under               
          certain conditions, such as when the amount of voltage applied to           
          the device substrate is of sufficient magnitude to produce a                
          strong electric field.                                                      
                           CLAIMS 2, 3, 7, 11, 12 and 16                              
               We are of the opinion that the rejection of these claims               
          under 35 U.S.C.  103 as obvious over Muramatsu, Piotrowski and             
          Taylor cannot be sustained and we will reverse the rejection.               




                                          10
