Claim:
1. An apparatus for removing halogen-containing residues from a substrate, comprising: at least one etch chamber; a load lock chamber interfaced with a heat module that is adapted to heat a substrate disposed in the load lock chamber; a transfer chamber having a robot disposed therein that is adapted to transfer the substrate between the etch chamber and the load lock chamber; an end point detector for detecting an end point of a volatile residues removal process performed in the heater module disposed in the load lock chamber; and a remote plasma source coupled to the load lock chamber; and a gas distribution ring formed as a vent passage sequentially coupled to the remote plasma source and further to a gas source disposed in the load lock chamber, wherein the gas distribution ring is fabricated by a material transmissive to heat generated from the heater module; wherein the load lock chamber is adapted to transfer the substrate between a substantially atmospheric environment and a vacuum environment of the transfer chamber.
