Abstract

A semiconductor package includes a substrate that includes a bonding pad, a first semiconductor chip disposed on the substrate, a second semiconductor chip disposed on a top surface of the first semiconductor chip that is opposite to the substrate, a chip pad disposed on the top surface of the first semiconductor chip, and a bonding wire that connects the chip pad to the bonding pad. The bonding wire includes a first upward protrusion and a second upward protrusion that are convexly curved in a direction away from the substrate. The second semiconductor chip has a first side surface between the first upward protrusion and the second upward protrusion.
