Patent ID: 8216762

Claim:
A method for manufacturing an array for a display device comprising steps of: (a) adhering a positive dry film resist, which has a positive photoresist resin layer over a supporting film, to a substrate such that the positive photoresist resin layer adheres on a surface of the substrate, wherein the positive photoresist resin layer was formed from a composition comprising an alkali soluble resin, a diazide based positive photosensitive compound, a first solvent and a second solvent wherein the first solvent has a boiling point sufficiently high such that a second solvent can be removed from the composition by heating while the first solvent is substantially retained in the composition; (b) releasing the supporting film from the positive photoresist resin layer adhered to the surface of the substrate; (c) exposing the positive photoresist resin layer to light; (d) developing the positive photoresist resin layer in an alkali developer; and (e) washing and drying the positive photoresist resin layer for removing the exposed region in the positive photoresist resin layer, wherein (f) baking the positive photoresist resin layer for removing the first solvent in the positive photoresist resin layer is performed before said developing step (d).
