摘要：
A die includes a substrate, a metal pad over the substrate, and a passivation layer covering edge portions of the metal pad. A metal pillar is formed over the metal pad. A portion of the metal pillar overlaps a portion of the metal pad. A center of the metal pillar is misaligned with a center of the metal pad.
