A semiconductor package includes a substrate, a semiconductor chip mounted on the substrate, an interposer chip on the semiconductor chip and including a redistribution pattern, a first pad on the interposer chip, a second pad on the interposer chip and spaced apart from the first pad, and a bonding wire electrically connected to the second pad and the first substrate. The second pad is electrically connected through the redistribution pattern to the first pad. The footprint of the interposer chip is greater than the footprint of the first semiconductor chip.
