Abstract
A method of fabricating a semiconductor package includes providing a wafer which includes an upper area having through silicon vias (TSVs) and a lower area not having the TSVs; mounting a semiconductor chip on the upper area of the wafer; forming a passivation layer to a predetermined thickness to cover the semiconductor chip; exposing the TSVs by removing the lower area of the wafer in a state where no support is attached to the wafer; and exposing a top surface of the semiconductor chip by partially removing the passivation layer.
