Methods of fabrication of lead frame-based semiconductor device packages 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 of the interposer substrate. 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.

Methods for packaging microelectronic devices and microelectronic devices formed using such methods are disclosed herein. One aspect of the invention is directed toward a method for packaging a microelectronic device that includes coupling an active side of a microelectronic die to a surface of a support member. The microelectronic die can have a backside opposite the active side, a peripheral side extending at least part way between the active side and the backside, and at least one through-wafer interconnect. The method can further include applying an encapsulant to cover a portion of the surface of the support member so that a portion of the encapsulant is laterally adjacent to the peripheral side, removing material from a backside of the microelectronic die to expose a portion of at least one through-wafer interconnect, and applying a redistribution structure to the backside of the microelectronic die.

Substrates for mounting microelectronic dies, methods for forming vias in such substrates, and methods for packaging microelectronic devices are disclosed herein. A method of manufacturing a substrate in accordance with one embodiment of the invention includes forming a conductive trace on a first side of a sheet of non-conductive material, and forming a via through the non-conductive material from a second side of the sheet to the conductive trace. The method further includes removing a section of the non-conductive material to form an edge of the non-conductive material extending across at least a portion of the via. In one embodiment, forming the edge across the via exposes at least a portion of the second conductive trace for subsequent attachment to a terminal on a microelectronic die.

In one embodiment, a stacked microelectronic device assembly can include a first known good packaged microelectronic device including a first interposer substrate. A first die and a first through-casing interconnects are electrically coupled to the first interposer substrate. A first casing at least partially encapsulates the first device such that a portion of each first interconnect is accessible at a top portion of the first casing. A second known good packaged microelectronic device is coupled to the first device in a stacked configuration. The second device can include a second interposer substrate having a plurality of second interposer pads and a second die electrically coupled to the second interposer substrate. The exposed portions of the first interconnects are electrically coupled to corresponding second interposer pads.

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.
