Patent ID: 7183192

Claim:
A method of forming a bump electrode in a semiconductor device, the method comprising: forming a passivation layer pattern having a first opening over a substrate including a metal wiring pattern formed thereon, wherein the passivation layer pattern comprises polyimide and the first opening partially exposes an upper surface of the metal wiring pattern; forming a photoresist pattern on the passivation layer pattern, the photoresist pattern having a second opening that exposes the first opening of the passivation layer pattern, wherein the first and second openings define a bump electrode opening; electroplating a metal in the bump electrode opening to define a bump electrode; and removing the photoresist pattern using a composition consisting essentially of about 13 to less than 30% by weight of monoethanolamine and more than 70 to about 87% by weight of dimethylacetamide based on a total weight of the composition.
