Abstract:
There is disclosed an electrostatic attracting method in which a direct-current voltage is applied to an electrode disposed at a table formed of a dielectric material to attract/hold a substrate onto a holding surface of the table with an electrostatic force produced thereby, the method comprising a first step of applying a voltage having a predetermined polarity to the electrode to charge the holding surface with an electric charge having a polarity different from that applied to the electrode, a second step of holding the substrate in contact with the holding surface to prevent electric charges charged on the holding surface from disappearing, and a third step of applying a voltage having a polarity different from that applied in the first step to the electrode in a state in which the substrate contacts the holding surface to produce an electric charge having the same polarity as that charged at the holding surface in the first step on the holding surface of the table, and attracting/holding the substrate with the electric charge together with the electric charge charged on the holding surface in the first step.
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.
