The present invention provides a biodegradable formulation and its use as a surfaces restoring agent, said formulation allows a substantial savings when restoring the existing paint on different surfaces, since it mainly cleans and restores the surface or paint contaminated by the environment, damaged due to the sun and the processes of the different industries, in addition to being friendly to the environment, making it a useful technology in any industrial branch that involves cleaning and restoring large areas. It is worth noting that the modifications to the original formula were made to optimize the results in the different applications and improve its biodegradability.

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-κ dielectric materials, and has a good selectivity.

The present invention relates to a photoresist stripper composition for manufacturing a display, and more particularly, to an integrated photoresist stripper composition which can be used in every process for manufacturing a display. More specifically, the photoresist stripper composition for manufacturing a display according to the present invention can be applied to all of transition metals and oxide semiconductor wirings, and has an excellent ability to remove modified photoresist after a hard bake process, and implant process, and a dry etch process have been performed. In particular, the photoresist stripper composition for manufacturing a display according to the present invention exhibits a corrosion inhibitory effect that has been further specialized for copper (Cu) wiring pattern edge portions which are susceptible to corrosion following dry-etching.
