Abstract: The current invention describes a formulation comprising of acetal or ketal as a solvent, a polyhydric alcohol, water and pH adjuster. These formulations should have a pH at least 7 or higher. Formulations in this invention can optionally contain water-soluble organic solvents as co-solvent, corrosion inhibitors and fluorides. The formulations in this invention can be used to remove post-etched organic and inorganic residue as well as polymeric residues from semiconductor substrates.

Abstract: Compositions containing certain organic solvents and a fluorine source are capable of removing photoresist and etching residue.

Abstract: The present invention relates to an aqueous cleaning composition used to remove unwanted organic and inorganic residues and contaminants from a substrate such as, for example, a semiconductor substrate. The cleaning composition comprises from about 0.01% to about 40% by weight of a salt selected from a guanidinium salt, an acetamidinium salt, a formamidinium salt, and mixtures thereof; water; and optionally a water soluble organic solvent. Compositions according to the present invention are free of an oxidizer and abrasive particles and are capable of removing residues from a substrate and, particularly, a substrate having silicon-containing BARC and/or photoresist residue.
