Abstract: A method of patterning a layer of dielectric material having a thickness greater than 1,000 Å, and typically a thickness greater than 5,000 Å. The method is particularly useful for forming a high aspect ratio via or a high aspect ratio contact including self-aligned contact structures, where the aspect ratio is typically greater than 3 and the feature size of the contact is about 0.25 &mgr;m or less. In particular, an organic, polymeric-based masking material is used in a plasma etch process for transferring a desired pattern through an underlying layer of dielectric material. The combination of masking material and plasma source gas must provide the necessary high selectivity toward etching of the underlying layer of dielectric material. The selectivity is preferably greater than 3:1, where the etch rate of the dielectric material is at least 3 times greater than the etch rate of the organic, polymeric-based masking material.

The metal is removed from the working electrode to recover the metal.

Examples of potential coil antenna configurations for achieving the desired power deposition pattern include constructing the coil antenna with a unitary or a segmented structure.

Abstract: A method for etching a tungsten containing layer 25 on a substrate 10 substantially anisotropically, with good etching selectivity, and without forming excessive passivating deposits on the etched features.
