Abstract: According to one embodiment, a solid removal process in a filter and a positive metal ion removal process in a positive metal ion-exchange resin column are performed sequentially through an etching acid waste liquid disposal circulation flow channel, the solid removal process is performed on an upstream side of the positive metal ion removal process, furthermore after the positive metal ion removal process, a negative metal ion removal process removing at least B using a chelate forming fiber or a chelate forming resin is performed on a downstream side of the etching acid waste liquid disposal circulation flow channel, thereby an etching acid waste liquid is recycled sequentially through the etching acid waste liquid disposal circulation flow channel.

Abstract: An apparatus for processing a substrate in which the substrate is successively processed with different kinds of process solution. A spin chuck supports the substrate. A driving source rotates the spin chuck A nozzle member supplies a first process solution prepared by mixing sulfuric acid and a hydrogen peroxide solution at a predetermined mixing ratio to the substrate. A switching mechanism selects the sulfuric acid, the hydrogen peroxide solution and the second process solution supplied to the nozzle member A concentration adjusting mechanism adjusts the ratio of sulfuric acid to the hydrogen peroxide solution, which collectively form the first process solution, supplied to the nozzle member. A control device controls the supply of sulfuric acid, the hydrogen peroxide solution and the second process solution, which is switched by the switching mechanism.

Abstract: A substrate is processed with a first process solution prepared by mixing sulfuric acid with a hydrogen peroxide solution, followed by processing the substrate with a second process solution. After the substrate is processed with the first process solution, the supply of sulfuric acid is stopped, with the hydrogen peroxide alone being supplied to the substrate. Then, the supply of the hydrogen peroxide solution is stopped, and the substrate is rinsed with a second process solution. The particular processing makes it possible to prevent the second process solution from reacting with sulfuric acid.
