    摘要: A die (or of a stack of die) is mounted over and elevated above a support, and is electrically connected to circuitry in the support. Pillars of electrically conductive material are formed on a set of bond pads at a mount side of the support, and the elevated die (or at least one die in the elevated stack of die) is electrically connected to the support, by traces of an electrically conductive material contacting interconnect pads on the die to the pillars, and through the pillars to the support. Also, tiered offset stacked die assemblies in a zig-zag configuration, in which the interconnect edges of a first (lower) tier face in a first direction, and the interconnect edges of a second (upper) tier, stacked over the first tier, face in a second direction, different from the first direction, are electrically connected to a support. Die in the first tier are electrically interconnected die-to-die, and the tier is electrically connected to a support, by traces of an electrically conductive material contacting interconnect pads on the die and a first set of bond pads on the support. Pillars of a electrically conductive material are formed on a second set of bond pads, and die in the second tier are electrically interconnected die-to-die, and the tier is electrically connected to the support, by traces of an electrically conductive material contacting interconnect pads on the die to the pillars, and through the pillars to the substrate.
