Abstract:
A cleaning composition and process for cleaning post-chemical mechanical polishing (CMP) residue and contaminants from a microelectronic device having said residue and contaminants thereon. The cleaning compositions include novel corrosion inhibitors. The composition achieves highly efficacious cleaning of the post-CMP residue and contaminant material from the surface of the microelectronic device without compromising the low-k dielectric material or the copper interconnect material.
Abstract:
Methods for removing a masking material, for example, a photoresist, and electronic devices formed by removing a masking material are presented. For example, a method for removing a masking material includes contacting the masking material with a solution comprising cerium and at least one additional oxidant. The cerium may be comprised in a salt. The salt may be cerium ammonium nitrate. The at least one additional oxidant may be a manganese, ruthenium, and/or osmium-containing compound.
Abstract:
Compositions and methods of using said composition for removing polymeric materials from surfaces, preferably cleaning contaminant buildup from a lithography apparatus without total disassembly of said apparatus.
Abstract:
Chemical mechanical polishing (CMP) compositions and single CMP platen process for the removal of copper and barrier layer material from a microelectronic device substrate having same thereon. The process includes the in situ transformation of a copper removal CMP composition, which is used to selectively remove and planarize copper, into a barrier removal CMP composition, which is used to selectively remove barrier layer material, on a single CMP platen pad.
