    Abstract: A method for forming a semiconductor structure includes curing a shape memory polymer in a first shape. The shape memory polymer is coupled to a conductive layer. The method further includes folding the shape memory polymer from the first shape into a second shape. The method also includes bonding a semiconductor wafer to the conductive layer while the shape memory polymer is in the second shape. The semiconductor wafer has first and second dies. The semiconductor wafer is then singulated to separate the first die from the second die. The method further includes expanding the shape memory polymer to its first shape and singulating the shape memory polymer to separate the first and second dies.

    Abstract: A semiconductor package includes a first layer including a semiconductor die and a shunt embedded within a first dielectric substrate layer, and metal pillars extending therethrough. The semiconductor package further includes a second layer stacked on the first layer, the second layer including a metal trace patterned on the first dielectric substrate layer, and a second dielectric substrate layer over the metal trace. The metal trace electrically connects a first portion of the shunt to a first metal pillar of the metal pillars and electrically connects a second portion of the shunt to a second metal pillar of the metal pillars. The semiconductor package further includes a base layer opposite the second layer relative the first layer, the base layer forming exposed electrical contact pads for the semiconductor package, the electrical contact pads providing electrical connections to the shunt, the metal pillars, and the semiconductor die.

    Abstract: An electronic device includes a package structure with opposite first and second sides spaced apart along a first direction, opposite third and fourth sides spaced apart along a second direction, opposite fifth and sixth sides spaced apart along a third direction, the first, second, and third directions being orthogonal to one another. A set of first leads extend outward from the first side along the first direction, a set of second leads extend outward from the second side along the first direction, and a thermal pad includes a first portion that extends along a portion of the fifth side, and a second portion that extends along a portion of the third side to facilitate cooling and visual solder inspection when soldered to a host printed circuit board.
