    Abstract: A system and method for removing photoresist or other organic compounds from semiconductor wafers is provided. Non-fluorinated reactant gases (O 2 , H 2 , H 2 O, N 2 etc.) are activated in a quartz tube by a medium pressure surface wave discharge. As the plasma jet impinges on a substrate, volatile reaction products (H 2 O, CO 2 , or low molecular weight hydrocarbons) selectively remove the photoresist from the surface. The medium pressure also enables high gas temperatures that provide an effective source of heat in the reactive zone on the wafer that enhances etch rates and provides a practical means of removing ion implanted photoresist.

    Abstract: A high plasma density etch process for etching an oxygen-containing layer overlying a non-oxygen containing layer on a workpiece in a plasma reactor chamber, by providing a chamber ceiling overlying the workpiece and containing a semiconductor material, supplying into the chamber a process gas containing etchant precursor species, polymer precursor species and hydrogen, applying plasma source power into the chamber, and cooling the ceiling to a temperature range at or below about 150 degrees C. The etchant and polymer precursor species contain fluorine, and the chamber ceiling semiconductor material includes a fluorine scavenger precursor material. Preferably, the process gas includes at least one of CHF3 and CH2F2. Preferably, the process gas further includes a species including an inert gas, such as HeH2 or Ar. If the chamber is of the type including a heated fluorine scavenger precursor material, this material is heated to well above the polymer condensation temperature, while the ceiling is cooled. In some cases, the plasma source power applicator is an inductive antenna overlying the semiconductor ceiling, and the ceiling has a cooling/heating apparatus contacting the ceiling through semiconductor rings. The inductive antenna in this case constitutes inductive elements between adjacent ones of the semiconductor rings.
