Abstract:
1. A resist and etching residue remover composition comprising: from about 1 wt % to about 30 wt % of N,N-diethylhydroxylamine from about 20 wt % to about 80 wt % of a two-carbon atom linkage alkanolamine compound having the formula wherein R from about 0.1 wt % to about 15 wt % of a corrosion inhibitor which comprises gallic acid, catechol, or an ethylenediamine tetracarboxylic acid compound; wherein the composition is substantially free of hydroxylamine and of fluoride ions, and the composition is capable of removing residue from a metal or metal alloy substrate or a metal or metal alloy substrate layer, while maintaining an acceptably low etch rate with respect to the metal or metal alloy substrate or substrate layer.
