摘要： A polishing slurry for metal comprises an oxidizer, a metal oxide dissolving agent, a metal inhibitor, and water, wherein the metal inhibitor is at least one of a compound having an amino-triazole skeleton and a compound having an imidazole skeleton. The use of the polishing slurry for metal makes it possible to raise the polishing speed sufficiently while keeping the etching speed low, restrain the generation of corrosion of the surface of a metal and dishing, and form a metal-film-buried pattern having a high reliability in the process of formation of wiring of semiconductor devices.

摘要： A process for production of a flexible laminated sheet having one or more laminated bodies each provided with a metal foil formed on one side of a resin film, the process comprising a coating step in which a varnish containing a polyamic acid and a solvent is coated onto the metal foil to form a coated film, a holding step in which the coated film formed on the metal foil is held, a drying step in which at least a portion of the solvent in the varnish is removed to form a layer composed of a resin composition, and a resin film-forming step in which the layer composed of the resin composition is heated to form a resin film containing a polyimide resin. The conditions for each step from the coating step up to the resin film-forming step are adjusted based on a target for the content of metal elements in the resin film.
