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 process for etching a substrate and removing etch residue deposited on the surfaces in the etching chamber has two stages. In the first stage, an energized first process gas is provided in the chamber, and in the second stage, an energized second process gas is provided in the chamber. The energized first process gas comprises SF6 and Ar, the volumetric flow ratio of SF6 to other components of the first process gas being from about 5:1 to about 1:10. The energized second process gas comprises CF4 and Ar, the volumetric flow ratio of CF4 to other components of the second process gas being from about 1:0 to about 1:10.
