More Information
Summary:Provided is a cleaning liquid composition which is useful for cleaning of a substrate or the like that has been subjected to a chemical mechanical polishing (CMP) process, etc in the production steps of an electronic device such as a semiconductor element. A cleaning liquid composition according to the present invention is used for the purpose of cleaning a substrate that has a Cu wiring, and comprises one or more basic compounds and one or more nitrogen-containing monocyclic heterocyclic aromatic compounds that contain one or more carboxyl groups or ester groups, provided that in cases where one or more amino groups are contained therein, only amino groups directly bonded to a nitrogen-containing heterocyclic rind are contained. This cleaning liquid composition has a hydrogen ion concentration (pH) of 8-12.
