On the efiects of anisotropic rheology on ice 8ow

An ethylenediaminetetraacetic acid or a mono- di- tri- or tetraammonium salt thereof residue cleaning composition removes photoresist and other residue from integrated circuit substrates. The balance of the composition is desirably made up of water, preferably high purity deionized water, or another suitable polar solvent. A process for removing photoresist or other residue from a substrate, such as an integrated circuit semiconductor wafer including titanium metallurgy, comprises contacting the substrate with the composition for a time and at a temperature sufficient to remove the photoresist or other residue from the substrate. Use of the ethylenediaminetetraacetic acid or a mono- di- tri- or tetraammonium salt thereof in the composition and process provides superior residue removal without attacking titanium or other metallurgy, oxide or nitride layers on the substrate.
