Abstract:
A plasma reactor comprising:a reactor chamber comprising a ceiling having a three-dimensionally shaped interior surface facing an interior portion of said reactor chamber;plasma source power coupling apparatus disposed about said ceiling and an RF power source to supply RF power to said plasma source power coupling apparatus;a process gas inletting apparatus and a process gas supply coupled to said inletting apparatus for furnishing a process gas containing etchant and polymer precursors;a support for holding an article to be processed inside said reactor chamber;a polymer-hardening precursor piece inside said chamber; anda heater capable of heating said polymer-hardening precursor piece to a temperature at which said polymer-hardening precursor piece donates polymer-hardening precursor material into a plasma, said temperature being greater than that temperature required to scavenge fluorine.
