Abstract

A semiconductor package includes a semiconductor chip, a lower redistribution layer disposed under the semiconductor chip, the lower redistribution layer including a plurality of lower insulating layers, a plurality of lower redistribution patterns, and a plurality of lower conductive vias, a lower passivation layer disposed under the lower redistribution layer and provided with a recess at a bottom surface of the lower passivation layer, an under bump metallization (UBM) pad disposed in the first recess, a UBM protective layer disposed in the first recess and connected to the lower conductive vias while covering a top surface and opposite side surfaces of the UBM pad, and an outer connecting terminal connected to a bottom surface of the UBM pad. The bottom surface of the UBM pad is positioned at a first depth from the bottom surface of the lower passivation layer.
