    摘要： A method and structure for protecting a flowable oxide insulator in a semiconductor by oxidizing sidewalls of the FOX insulator, optionally nitridizing the oxidized FOX sidewalls, and then covering all surfaces of a trough or plurality of troughs in the FOX insulator, including the sidewalls, with a conductive secondary protective layer. In a multiple layer damascene structure, the surface of the FOX insulator is also oxidized, an additional oxide layer is deposited thereon, and a nitride layer deposited on the oxide layer. Then steps are repeated to obtain a comparable damascene structure. The materials can vary and each damascene layer may be either a single damascene or a dual damascene layer.

    摘要： Resist developers can attack some advanced dielectric materials such as silsesquioxane materials which can be used as an insulator between a surface of an integrated circuit chip and wiring layers formed on the surface of the dielectric material. A first protective layer is formed in situ on the dielectric material, such as by exposing the material to an oxygen-containing or flourine containing plasma. Also, by performing a resist stripping or etching process in which a reactant material is supplied externally or liberated from the dielectric material, an extremely thin surface protective covering of an intermediate material may be formed which is impervious to resist developers or any of a plurality of other materials which may damage the flowable oxide material. The first protective layer and the surface protective covering can be formed by essentially identical processes. A dual Damascene process for forming robust connections and vias to the chip can thus be made compatible with advanced dielectrics having particularly low dielectric constants to minimize conductor capacitance and support fast signal propagation and noise immunity even where conductors are closely spaced to each other.
