The invention further concerns a rinse aid composition for rinsing the surface and a method for removing soil from the surface during a rinsing step.

Provided are a cleaning agent and a preparation method and the use thereof. The cleaning agent is prepared from the following raw materials comprising the following mass fraction of components: 0.5%-20% of an oxidant containing iodine, 0.5%-20% of an etchant containing boron, 1%-50% of a pyrrolidinone solvent, 1%-20% of a corrosion inhibitor, 0.01%-5% of a metal ion-free surfactant, and water, with the sum of the mass fraction of each component being 100%, the pH of the cleaning agent is 7.5-13.5, and the corrosion inhibitor is one or more of a benzotriazole corrosion inhibitor, a hydrazone corrosion inhibitor, a carbazone corrosion inhibitor and a thiocarbohydrazone corrosion inhibitor. The cleaning agent can efficiently remove nitrides from hard mask residues with little effects on metals and low-K dielectric materials, and has a good selectivity.

A removal composition and process for cleaning post-chemical mechanical polishing (CMP) contaminants and particles from a microelectronic device having said particles and contaminants thereon. The removal compositions include at least one at least one organic additive; at least one metal chelating agent; and at least one polyelectrolyte. The composition achieves highly efficacious removal of the particles and CMP contaminant material from the surface of the microelectronic device without compromising the low-k dielectric, silicon nitride, and metal containing layers such as tungsten-containing layers.

The invention relates to cleaning deposits of various natures from metal, glass and ceramic surfaces of industrial equipment and can be used for the removal of such deposits, as metal oxides (iron, chromium, nickel, etc.), carbonate and salt deposits, asphalt-tar-paraffin deposits and deposits of an oily nature, deposits of organic and biological nature (bacterial deposits). The proposed solution for removing deposits of different natures comprises hydrogen peroxide, complexing agent, calixarene and water in the following quantitative ratio, wt. %: hydrogen peroxide, 2-90; complexing agent, 3-30; calixarene, 0.01-10; water, the balance. EFFECT: increased degree of cleaning off deposits of various natures with simultaneous reduction of solution aggressiveness to structural materials.
