                                                       DECISION ON APPEAL                                                               
                        This is an appeal from the final rejection of claims 18 through 23.                                             
                        The disclosed invention relates to a method of producing a vertically oriented light emitting                   
               diode (LED) using an indium gallium nitride active layer sandwiched between two thin undoped                             
               layers of gallium nitride in a nitrogen atmosphere on a silicon carbide substrate.  A thin layer of                      
               aluminum gallium nitride is also formed in the nitrogen atmosphere.  All other layers of the LED are                     
               formed in a hydrogen atmosphere.
