Removing agent composition for a photoresist and process for producing a semiconductor integrated circuit

摘要

A removing agent composition for a photoresist comprising 0.01 to 20% by weight of a quaternary ammonium hydroxide, 1 to 80% by weight of a nucleophilic amine having an oxidation-reduction potential, 0.5 to 20% by weight of a sugar and/or a sugar alcohol, and water in the remaining amount; and a process for producing a semiconductor integrated circuit comprising removing a photoresist applied onto an inorganic substrate by using the above removing agent composition. A layer of a photoresist applied onto an inorganic substrate, a layer of a photoresist remaining after dry etching of an inorganic substrate which is masked by the layer, or residues of a layer of a photoresist remaining after dry etching of an inorganic substrate which is masked by the layer and subsequent ashing of the layer can easily be removed at a low temperature in a short time. The wiring material of the circuit is not corroded at all, and ultra-fine working can be performed.
