摘要:
In a composition for removing a polymeric contaminant that may remain on an apparatus for manufacturing a semiconductor device and a method of removing a polymeric contaminant using the composition, the composition includes from about 5 to 10 percent by weight of a fluoride salt, from about 5 to 15 percent by weight of an acid or a salt thereof, and from about 75 to 90 percent by weight of an aqueous solution of glycol. The composition can effectively remove the polymeric contaminant from the apparatus within a relatively short period of time, and suppress damages to parts of the apparatus.

A composition for removing a photoresist includes about 5 to about 20 percent by weight of an alcoholamide compound, about 15 to about 60 percent by weight of a polar aprotic solvent, about 0.1 to about 6 percent by weight of an additive, and pure water. The alcoholamide compound is chemically structured as follows: where R1 is a hydroxyl group or a hydroxyalkyl group, and R2 is a hydrogen atom or a hydroxyalkyl group.

An etching solution for silicon oxide may be used in a process for enlarging an opening formed through a silicon oxide layer. The etching solution includes about 0.2 to about 5.0 percent by weight of a hydrogen fluoride solution, about 0.05 to about 20.0 percent by weight of an ammonium fluoride solution, about 40.0 to about 70.0 percent by weight of an alkyl hydroxide solution and remaining water. The etching solution may etch the silicon oxide layer without damage to a metal silicide layer exposed by the opening.

The cleaning composition comprises about 80 to 99.8999 percent by weight of an ammonium fluoride aqueous solution, about 0.1 to 5 percent by weight of a buffering agent, and about 0.0001 to 15 percent by weight of a corrosion-inhibiting agent. A method of preparing the cleaning composition, a method of cleaning a substrate using the cleaning composition, and a method of manufacturing a semiconductor device using the cleaning composition are also disclosed.
摘要:
A method of manufacturing a semiconductor device includes preparing a substrate on which a fuze line containing copper is formed. The method further includes cutting the fuze line by emitting a laser beam, and applying a composition for etching copper to the substrate to finely etch a cutting area of the fuze line and to substantially remove at least one of a copper residue and a copper oxide residue remaining near the cutting area. The composition for etching copper includes about 0.01 to about 10 percent by weight of an organic acid, about 0.01 to 1.0 percent by weight of an oxidizing agent, and a protic solvent.
