Abstract: Apparatus for testing semiconductor devices comprising die stacks, the apparatus comprising a substrate having an array of pockets in a surface thereof arranged to correspond to conductive elements protruding from a semiconductor device to be tested. The pockets include conductive contacts with traces extending to conductive pads, which may be configured as test pads, jumper pads, edge connects or contact pads. The substrate may comprise a semiconductor wafer or wafer segment and, if the latter, multiple segments may be received in recesses in a fixture. Testing may be effected using a probe card, a bond head carrying conductive pins, or through conductors carried by the fixture.

Abstract: An interconnect assembly includes a bond pad and an interconnect structure configured to electrically couple an electronic structure to the bond pad. The interconnect structure physically contacts areas of the bond pad that are located outside of a probe contact area that may have been damaged during testing. Insulating material covers the probe contact area and defines openings spaced apart from the probe contact area. The interconnect structure extends through the openings to contact the bond pad.

Abstract: Method for packaging a semiconductor die assemblies. In one embodiment, a method is directed to packaging a semiconductor die assembly having a first die and a plurality of second dies arranged in a stack over the first die, wherein the first die has a peripheral region extending laterally outward from the stack of second dies. The method can comprise coupling a thermal transfer structure to the peripheral region of the first die and flowing an underfill material between the second dies. The underfill material is flowed after coupling the thermal transfer structure to the peripheral region of the first die such that the thermal transfer structure limits lateral flow of the underfill material.

Abstract: Systems and methods are described for improved heat dissipation of the stacked semiconductor dies by including metallic thermal pads between the dies in the stack. In one embodiment, the thermal pads may be in direct contact with the semiconductor dies. Heat dissipation of the semiconductor die stack can be improved by a relatively high thermal conductivity of the thermal pads that directly contact the adjacent silicon dies in the stack without the intervening layers of the low thermal conductivity materials (e.g., passivation materials). In some embodiments, the manufacturing yield of the stack can be improved by having generally coplanar top surfaces of the thermal pads and under-bump metallization (UBM) structures.
