SEMICONDUCTOR PACKAGE

A semiconductor package includes a first substrate having a first surface and a second surface opposite to the first surface, a first semiconductor chip on the first surface of the first substrate, a second semiconductor chip on the first surface of the first, a stiffener on the first semiconductor chip and the second semiconductor chip, and an encapsulant on the first surface of the first substrate. The first substrate includes a plurality of first pads on the first surface thereof and a plurality of second pads on the second surface thereof. The first semiconductor chip is connected to a first group of first pads of the plurality of first pads. The second semiconductor chip is connected to a second group of first pads of the plurality of first pads. The stiffener covers a space between the first semiconductor chip and the second semiconductor chip. The encapsulant covers at least a sidewall of each of the first and second semiconductor chips and the stiffener.
