Abstract
A semiconductor device includes a semiconductor die. The semiconductor die includes a device layer, an interconnect layer over the device layer, a conductive pad over the interconnect layer, a conductive seed layer directly on the conductive pad, and a passivation layer encapsulating the conductive pad and the conductive seed layer. The conductive pad is between the interconnect layer and the conductive seed layer.
