摘要:
A lead frame-based semiconductor device package including at least one land grid array package. At least one semiconductor die is mounted to an interposer substrate, with bond pads of the semiconductor die connected to terminal pads on the same side of the interposer substrate as the at least one semiconductor die. The terminal pads of the interposer substrate may be electrically connected to both a peripheral array pattern of lands and to a central, two-dimensional array pattern of pads, both array patterns located on the opposing side of the interposer substrate from the at least one semiconductor die. The assembly is overmolded with an encapsulant, leaving the opposing side of the interposer substrate free of encapsulant. Lead fingers of a lead frame superimposed on the opposing side of the interposer substrate are bonded directly to the land grid array lands. Two land grid array packages as previously described may be superimposed on opposing sides of lead fingers of a lead frame disposed therebetween and electrically connected thereto. Methods of fabrication are also disclosed.

Electronic devices include a substrate with first and second pairs of conductive traces extending in or on the substrate. A first conductive interconnecting member extends through a hole in the substrate and communicates electrically with a first trace of each of the first and second pairs, while a second conductive interconnecting member extends through the hole and communicates electrically with the second trace of each of the first and second pairs. The first and second interconnecting members are separated from one another by a distance substantially equal to a distance separating the conductive traces in each pair. Electronic device assemblies include a transmitting device configured to transmit a differential signal through a conductive structure to a receiving device. The conductive structure includes first and second pair of conductive traces with first and second interconnecting members providing electrical communication therebetween.

A semiconductor device package includes a land grid array package. At least one semiconductor die is mounted to an interposer substrate, with bond pads of the semiconductor die connected to terminal pads on the same side of the interposer substrate as the at least one semiconductor die. Terminal pads of the interposer substrate may be electrically connected to either or both of a peripheral array pattern of lands and to a central, two-dimensional array pattern of pads, both array patterns located on the opposing side of the interposer substrate from the at least one semiconductor die. Additional components, active, passive or both, may be connected to pads of the two-dimensional array to provide a system-in-a-package. Lead fingers of a lead frame may be superimposed on the opposing side of the interposer substrate, bonded directly to the land grid array land and wire bonded to pads as desired for repair or to ease routing problems on the interposer. The land grid array package may be mounted to a carrier substrate, and the lands wire bonded to conductive pads on the carrier substrate. Methods of fabrication are also disclosed.

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.

A semiconductor component includes a chip on board leadframe, a semiconductor die back bonded and wire bonded to the leadframe, an encapsulant on the die and an area array of terminal contacts on the leadframe. The leadframe includes leadfingers, interconnect bonding sites for wire bonding the die, terminal bonding sites for the terminal contacts, and bus bars which electrically connect selected leadfingers to one another. The interconnect bonding sites are located on the leadframe relative to the bus bars such that shorting to the bus bars by wire interconnects is eliminated. A method for fabricating the component includes the steps of attaching the die to the leadframe, bonding the wire interconnects to the die and to the interconnect bonding sites, forming the encapsulant, and then forming the terminal contacts on the terminal bonding sites.
