Abstract: A semiconductor device includes a semiconductor substrate, a conductive pad over the semiconductor substrate, a conductive bump, a conductive cap over the conductive bump, and a passivation layer. The conductive pad is over the semiconductor substrate. The conductive bump is over the conductive pad, wherein the conductive bump has a stepped sidewall structure including a lower sidewall, an upper sidewall laterally offset from the lower sidewall, and an intermediary surface laterally extending from a bottom edge of the upper sidewall to a top edge of the lower sidewall. The conductive cap is over the conductive bump. The passivation layer is over the semiconductor substrate and laterally surrounds the conductive bump, wherein the passivation layer has a top surface higher than the intermediary surface of the stepped sidewall structure of the conductive bump and lower than a top surface of conductive cap.
