发明名称 RESIST STRIPPING COMPOSITIONS AND METHODS FOR MANUFACTURING ELECTRICAL DEVICES
摘要 A liquid composition comprising (A) at least one polar organic solvent, selected from the group consisting of solvents exhibiting in the presence of from 0.06 to 4% by weight of dissolved tetramethylammonium hydroxide (B), the weight percentage being based on the complete weight of the respective test solution (AB), a constant removal rate at 50° C. for a 30 nm thick polymeric barrier anti-reflective layer containing deep UV absorbing chromophoric groups, (B) at least one quaternary ammonium hydroxide, and (C) at least one aromatic amine containing at least one primary amino group, a method for its preparation and a method for manufacturing electrical devices, employing the liquid composition as a resist stripping composition and its use for removing negative-tone and positive-tone photoresists and post etch residues in the manufacture of 3D Stacked Integrated Circuits and 3D Wafer Level Packagings by way of patterning Through Silicon Vias and/or by plating and bumping.
