Abstract:
A wiring structure includes a redistribution layer and an electrical pad. The redistribution layer includes a passivation layer and a metal layer. The metal layer is embedded in the passivation layer, and the passivation layer defines an opening to expose a portion of the metal layer. The electrical pad is disposed in the opening of the passivation layer and on the metal layer. The electrical pad includes a seed layer, a conductive layer, a barrier layer and an anti-oxidation layer.
