Latest Patents

Among his latest patents is an assembly having stacked die mounted on a substrate. This invention focuses on metal rerouting interconnects at one or more sides of a die or multiple die segments, which can form edge bonding pads for electrical connections. The insulation can be applied to the surfaces of the die or multiple die segments after optional thinning and singulation. Openings can be made in the insulation to access the electrical connection pads. Once the die or segments are stacked, vertically adjacent components can be electrically interconnected using a flexible bond wire or bond ribbon attached to an exposed electrical connection pad. Additionally, electrically conductive polymer or epoxy filaments can be applied to the stack to enhance connectivity.

Another patent by Almen provides an apparatus for vertically interconnecting semiconductor die, integrated circuit die, or multiple die segments. This invention also includes metal rerouting interconnects that extend to one or more sides of the die or segment, allowing for the creation of edge bonding pads for external electrical connections. After the metal rerouting interconnect is added, the wafer is thinned, and each die or segment is singulated. Insulation is then applied, and openings are made above the desired electrical connection pads before stacking the segments. This innovative approach allows for efficient electrical interconnections between vertically adjacent segments.
