Patent ID: 8398813

Claim:
A processing apparatus for removing an oxide film from a surface of an object to be processed, the processing apparatus comprising: a low-temperature processing container for accommodating the object to be processed therein; a plasma-generating gas source for feeding a plasma-generating gas; a plasma-generating unit for changing the plasma-generating gas into plasmatic gas; an additive gas feeding unit arranged in the low-temperature processing container for feeding an additive gas having element F into the plasmatic gas that has been fed to a position of the low-temperature processing container; and a heating processing container for heating the object to be processed; wherein the plasmatic gas that has been fed into the low-temperature processing container and the additive gas having element F that has been activated by being fed into the plasmatic gas are adapted to be supplied onto the oxide film on the surface of the object that has been accommodated in the low-temperature processing container, and to react with the oxide film under an unheated condition in order to form a reaction-product film having elements Si, N, H, F, and O mixed therein, and wherein the heating processing container is adapted to heat the object on which the reaction-product film has been formed, in order to evaporate and remove the reaction-product film.
