    Abstract: A fluorine-free integrated process for plasma etching aluminum lines in an integrated circuit structure including an overlying anti-reflection coating (ARC) and a dielectric layer underlying the aluminum, the process being preferably performed in a single plasma reactor. The ARC open uses either BCl3/Cl2 or Cl2 and possibly a hydrocarbon passivating gas, preferably C2H4. The aluminum main etch preferably includes BCl3/Cl2 etch and C2H4 diluted with He. The dilution is particularly effective for small flow rates of C2H4. An over etch into the Ti/TiN barrier layer and part way into the underlying dielectric may use a chemistry similar to the main etch. A Cl2/O2 chamber cleaning may be performed, preferably with the wafer removed from the chamber and after every wafer cycle.

    Abstract: A method is provided for etching a dielectric structure. The dielectric structure comprises: (a) a layer of undoped silicon oxide or F-doped silicon oxide; and (b) a layer of C,H-doped silicon oxide. The dielectric structure is etched in a plasma-etching step, which plasma-etching step is conducted using a plasma source gas that comprises nitrogen atoms and fluorine atoms. As one example, the plasma source gas can comprise a gaseous species that comprises one or more nitrogen atoms and one or more fluorine atoms (e.g., NF3). As another example, the plasma source gas can comprise (a) a gaseous species that comprises one or more nitrogen atoms (e.g., N2) and (b) a gaseous species that comprises one or more fluorine atoms (e.g., a fluorocarbon gas such as CF4). In this etching step, the layer of C,H-doped silicon oxide is preferentially etched relative to the layer of undoped silicon oxide or F-doped silicon oxide. The method of the present invention is applicable, for example, to dual damascene structures.
