    摘要: A method for post-etch copper cleaning uses a hydrogen plasma with a trace gas additive constituting about 3-10 percent of the plasma by volume to clean a copper surface exposed by etching. The trace gas may be atomic nitrogen or other species having an atomic mass of 15 or greater. The trace gas adds a sputtering aspect to the plasma cleaning and removes polymeric etch by-products and polymeric and other residuals formed during the deposition of dielectric materials or etch stop layers over the copper surface. An anti-corrosion solvent may be used to passivate the copper surface prior to formation of the dielectric materials or etch stop layers.

    摘要: A process for plasma etching of contact and via openings in low-k organic polymer dielectric layers is described which overcomes problems of sidewall bowing and hardmask pattern deterioration by etching the organic layer in a high density plasma etcher with a chlorine/inert gas plasma. By adding chlorine to the oxygen/inert gas plasma, the development of an angular aspect or faceting of the hardmask pattern edges by ion bombardment is abated. Essentially vertical sidewalls are obtained in the openings etched in the organic polymer layer while hardmask pattern integrity is maintained. The addition of a passivating agent such as nitrogen, BCl.sub.3, or CHF.sub.3 to the etchant gas mixture further improves the sidewall profile by reducing bowing through protective polymer formation.

    摘要: A method for preventing the formation of contaminating polymeric films on the backsides of semiconductor substrates includes providing an oxygen-impregnated focus ring and/or an oxygen-impregnated chuck that releases oxygen during etching operations. The method further provides delivering oxygen gas to the substrate by mixing oxygen in the cooling gas mixture, maintaining the focus ring at a temperature no greater than the substrate temperature during etching and cleaning the substrate using a two step plasma cleaning sequence that includes suspending the substrate above the chuck.

The Critical Dimensions of the seal ring are selected with respect to the CD of other device features, such a seal vias, such that the difference in etch sensitivity between the created seal ring and the via holes is removed. All etch of the simultaneously etched features is completed at the same time, avoiding punch through of an underlying layer of etch stop material.

    摘要: A process used to prevent attack of an aluminum based structure, exposed in a non-fully landed via hole, from solvents used during the wet stripping cycle, performed to remove the via hole defining photoresist shape, has been developed. The process features the formation of a protective aluminum oxide layer, on the exposed side of the aluminum based structure, via use of a plasma treatment, performed in an H.sub.2 O/N.sub.2 ambient. The H.sub.2 O/N.sub.2 plasma treatment procedure is performed after a dry plasma, photoresist stripping step, but prior to a final wet photoresist stripping step. The aluminum oxide layer offers protection of the exposed regions of the aluminum structure, located in the non-fully landed via hole, from reaction or corrosion, that can result from exposure of aluminum to the solvents used in the final wet photoresist stripping cycle.
