Abstract: A semiconductor package includes a wiring substrate that includes a wiring pattern, a dielectric pattern that covers the wiring pattern, a substrate pad on the dielectric pattern and including a recess that extends from a top surface of the substrate pad toward an inside of the substrate pad, a metal layer on a bottom surface of the recess and spaced apart from an inner lateral surface of the recess, and a protection layer on the dielectric pattern and covering the substrate pad. The substrate pad penetrates the dielectric pattern to come into connection with the wiring pattern. The protection layer exposes at least a portion of the metal layer. The protection layer extends from the top surface of the substrate pad to fill a space between a lateral surface of the metal layer and the inner lateral surface of the recess.
