Abstract: Method and apparatus for abating F2 from by-products generated during cleaning of a processing chamber. F2 abatement is efficiently performed by directly injecting H2 in line with a foreline exiting the processing chamber. A tube which is highly resistant to oxidation and corrosive gases, even at high temperature, is connected in line with the foreline as part of the exhaust line of the processing chamber. A cooling jacket may be provided for cooling the tube, since the reaction between F2 and H2 is exothermic. A pressure monitoring arrangement may also be employed to insure that pressure within a hydrogen line, that feeds the injection of H2 into the tube, does not exceed a predetermined pressure value.
