Solution for removing residue after semiconductor dry process and method of removing the residue using the same

Abstract

The present invention provides a residue-removing solution for use after a dry process, the residue-removing solution being capable of preventing minute cracks on a Cu surface, which has heretofore been unresolved with known polymer-removing solutions; and a method for manufacturing semiconductor devices using the residue-removing solution. More specifically, the invention relates to a residue-removing solution for removing residues present on semiconductor substrates after dry etching and/or ashing, the solution containing water and at least one component selected from the group consisting of (a) a keto acid, (b) a keto acid salt, and (c) an aldehyde acid salt; and a method for removing residues using the residue-removing solution.
