A photoresist residue remover composition is provided that removes a
photoresist residue formed by a resist ashing treatment after dry etching
in a step of forming, on a substrate surface, wiring of any metal of
aluminum, copper, tungsten, and an alloy having any of these metals as a
main component, the composition including one or two or more types of
inorganic acid and one or two or more types of inorganic fluorine
compound. There is also provided a process for producing a semiconductor
circuit element wherein, in a step of forming wiring of any metal of
aluminum, copper, tungsten, and an alloy having any of these metals as a
main component, the photoresist residue remover composition is used for
removing a photoresist residue formed by a resist ashing treatment after
dry etching.
