Abstract
A semiconductor package can include a substrate and a semiconductor chip on the substrate. A first molding portion can cover the semiconductor chip and can include a first sidewall and a second sidewall opposite each other. A second molding portion can extend on the substrate along the first sidewall and along the second sidewall, where the first molding portion can include a nonconductive material, and the second molding portion can include a conductive material.
