A method for mounting and electrically interconnecting a stack of semiconductor dice on edge to a circuit board is provided. The method forms interconnects adapted to mount each die on edge and establish an electrical connection between contact locations on the die (e.g., bond pads) and corresponding connection points on the circuit board. Each interconnect includes a substrate formed of a material such as silicon or ceramic having a low thermal coefficient of expansion (TCE). Trenches are etched or sawed into the substrate and are then filled with a metal to form conductive traces. Each conductive trace includes contact bump for contacting a contact location on a corresponding die. Z-axis conductive adhesives are used to attach the dice to the interconnects and the interconnects to the circuit board. |
