titleOfInvention | Residue removal liquid after semiconductor drying process and residue removal method using the same |
abstract | The present invention provides a residue removal liquid after a dry process comprising a surface protecting agent capable of preventing cracking and roughness of the Cu surface and preventing oxidation of the Cu surface, which could not be solved with a conventional polymer stripping liquid, and using the semiconductor using the same. Provided is a method of manufacturing a device. As a removal liquid of the residue which exists in a semiconductor substrate after dry etching and / or ashing, (1) Hetero 5-membered ring aromatic compound which has a structure represented by Formula: = N? NH? It is a compound contained as a basic skeleton, pH of this aqueous solution (10 ppm, 23 degreeC) is 7 or less, and (2) Formula:? N = C (SH)? X? (Wherein X is NH, O or S It is a compound containing the hetero 5-membered ring compound which has a structure represented by the following formula as a basic skeleton, pH of this aqueous solution (10ppm, 23 degreeC) is 7 or less, and (3) At least 1 nitrogen atom (N) The branched compound is a compound containing a hetero 6-membered ring aromatic compound as a basic skeleton, and the Cu surface protective agent composed of at least one compound selected from the group consisting of pH 7 of the aqueous solution (10 ppm, 23 ° C.) and Cu (copper) Compounds and water capable of forming complexes or chelates with And include, but pH is about 4? 9, residue remover. |
