Abstract: An assembly method is disclosed that includes providing a substrate, securing a first semiconductor device on a first surface thereof, and superimposing at least a second semiconductor device at least partially over the first semiconductor device. An outer peripheral portion of the second semiconductor device overhangs both the first semiconductor device and the substrate. Discrete conductive elements are placed between the outer peripheral portion of the second semiconductor device and a second surface of the substrate. Intermediate portions of the discrete conductive elements pass outside of a side surface of the substrate. Assemblies and packaged semiconductor devices that are formed in accordance with the method are also disclosed.

Abstract: A semiconductor package includes a semiconductor die having a circuit side and a back side, a multi layered leadframe attached to the die, a dense array of terminal contacts in electrical communication with the die, and a plastic body encapsulating the die and the leadframe. The leadframe includes circuit side leads attached to the circuit side of the die, and back side leads located proximate to the back side of the die. Both the circuit side leads and the back side leads are wire bonded to bond pads on the die. In addition, the back side leads provide electrical paths between the bond pads and selected terminal contacts that would otherwise be inaccessible due to line/space design rules. A method for fabricating the package includes the steps of: attaching the die to the circuit side leads, attaching the back side leads to the circuit side leads, wire bonding the die to the leads, encapsulating the die, and then forming the terminal contacts.
