    摘要: The present invention relates to a semi-aqueous cleaning composition used to remove unwanted organic and inorganic residues and contaminants from semiconductor substrates. The cleaning composition comprises a buffering system comprising a polyprotic acid having at least three carboxylic acid groups with a pKa value of about 5 to about 7. The composition also comprises a polyhydric solvent, such as glycerol. A fluoride ion source is also included in the cleaning compositions of the present invention and is principally responsible for removing inorganic residues from the substrate. The cleaning compositions of the present invention have a low toxicity and are environmentally acceptable.

    摘要: A residue cleaning composition includes: (a) water; (b) a fluoride; (c) a pH buffer system including an organic acid and a base. The organic acid can be an aminoalkylsulfonic acid and/or an aminoalkylcarboxylic acid. The base can be an amine and/or a quaternary alkylammonium hydroxide. The composition is substantially free of an added organic solvent and has a pH ranging from about 5 to about 12. A method of removing residue from a substrate includes contacting the residue with the cleaning composition. A method for defining a pattern includes etching the pattern through a photoresist into a substrate, heating the patterned substrate to a temperature sufficient to ash the photoresist and provide a residue, and removing the residue by contacting the residue with the cleaning composition.
