A passivation layer pattern having an opening is formed on a substrate having a metal wiring pattern formed thereon. The opening partially exposes an upper surface of the metal wiring pattern. A photoresist pattern is formed on the passivation layer pattern. The photoresist pattern has an opening that exposes the opening of the passivation layer pattern, and metal is electroplated in the openings to form a bump electrode. The photoresist pattern is removed using a composition including monoethanolamine and dimethylacetamide.
