Then, a photoresist protection layer is formed outside the metal member, and a selective exposure treatment is performed such that corresponding locations of the photoresist protection layer being exposed is subject to a photochemical reaction. The photoresist protection layer is developed, and after the photoresist protection layer is partially dissolved, portions of the metal member at the corresponding locations are simultaneously exposed. The exposed portions of the metal member are etched, and residual portions of the photoresist protection layer are removed to form the metal line provided on the insulator.
