                                               DECISION ON APPEAL                                                        


                     This is a decision on appeal from the final rejection of claims 1-9.                                
                     The invention is directed to a semiconductor device having an impurity region                       
              under an isolation region.  The invention seeks to solve the prior art problem wherein                     
              source/drain impurity ions deposited in a well region, below a partial oxide film, would                   


              change the resistance value of the body resistance of the well region.  This would cause                   
                                                           1
