Abstract: A method of manufacturing a display substrate may include the following steps: forming a drain electrode on a pixel area of a substrate; forming a pad electrode on a pad area of the substrate; forming an inorganic insulation layer that covers the drain electrode and the pad electrode; forming an organic insulation member that has a first thickness at the pixel area of the substrate, has a second thickness less than the first thickness at the pad area of the substrate, exposes a first portion of the inorganic insulation layer on the drain electrode, and exposes a second portion of the inorganic insulation layer on the pad electrode; removing the first portion of the inorganic insulation layer and the second portion of the inorganic insulation layer; and partially removing the organic insulation member.

Abstract: A substrate processing apparatus includes a first process chamber in which a target substrate is processed, a first tank connected to the first process chamber to supply a first chemical to the first process chamber, a second process chamber in which the target substrate is processed, and a second tank connected to the second process chamber to supply a second chemical to the second process chamber. A metal ion contained in the first chemical supplied to the first process chamber has an ion concentration greater than an ion concentration of the metal ion contained in the second chemical supplied to the second process chamber.
