Patent ID: 7144848

Claim:
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 1 , R 1 ′, R 2 , R 2 ′, and R 3 are, independently in each case, hydrogen or a linear, branched, or cyclic hydrocarbon containing from 1 to 7 carbon atoms, wherein Z is a group having the formula -(-Q-CR 1 R 1 ′—CR 2 R 2 ′—) m —, such that m is a whole number from 0 to 3, R 1 , R 1 ′, R 2 , and R 2 ′ are independently defined in each repeat unit, if m>1, within the parameters set forth for these moieties above, and Q is independently defined in each repeat unit, if m>1, each Q being independently either —O— or —NR 3 —, and wherein X and Y are, independently in each case, hydrogen, a C 1 –C 7 linear, branched, or cyclic hydrocarbon, or a group having the formula —CR 1 R 1 ′—CR 2 R 2 ′-Z-F, with F being either —O—R 3 or —NR 3 R 4 , where R 4 is defined similarly to R 1 , R 1 ′, R 2 , R 2 ′, and R 3 above, and with Z, R 1 , R 1 ′, R 2 , R 2 ′, and R 3 defined as above, or wherein X and Y are linked together form a nitrogen-containing heterocyclic C 4 –C 7 ring, wherein the two-carbon atom linkage alkanolamine compound comprises 2-(2-aminoethylamino)-ethanol; and 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.
