Abstract:
A semiconductor device has a leadframe with first and second opposing surfaces and a plurality of notched fingers. The leadframe is mounted to a carrier. A first semiconductor die is mounted over the carrier between the notched fingers. Conductive TSVs are formed through the first semiconductor die. A bond wire is formed between a first contact pad on the first semiconductor die and notched finger. The conductive TSV are electrically connected to the bond wires. An encapsulant is deposited over the first semiconductor die and notched fingers. Bumps are formed over the first surface of the leadframe. The carrier is removed and the leadframe is singulated. The leadframe and first semiconductor die is mounted to a substrate. A second semiconductor die is mounted to a second contact pad on the first semiconductor die. A third semiconductor die is mounted to the second surface of the leadframe.
