Post plasma etch/ash residue and silicon-based anti-reflective coating remover compositions containing tetrafluoroborate ion

摘要

A microelectronic cleaning compositions of: a) from about 80% to about 99% by weight of the composition of at least one organic sulfone; b) from about 0.5% to about 19% by weight of the composition of water; and c) from about 0.5% to about 10% by weight of the composition of at least one component providing tetrafluoroborate ion, and d) optionally at least one polyhydric alcohol is especially useful to clean etch/ash residues from microelectronic substrates or device having both Si-based anti-reflective coatings and low-k dielectrics.
