1. A method of adjusting the emission of vacuum ultraviolet (VUV) radiation from a plasma in a semiconductor processing chamber, the method comprising:

  • generating a plasma in the processing chamber, the plasma comprising a VUV-emitter gas and a collisional energy absorber gas, the plasma emitting VUV radiation; and

    adjusting the emission of VUV radiation from the plasma by altering the concentration ratio of the VUV-emitter gas to collisional energy absorber gas in the plasma.
