Patent ID: 8525352

Claim:
A multi-die package comprising: at least one die pad; a first semiconductor die disposed on the least one die pad, the first semiconductor die including an upper surface having a first plurality of bond pads thereon; a second semiconductor die disposed on the least one die pad, the second semiconductor die including an upper surface having a second plurality of bond pads thereon, the upper surface of the first semiconductor die and the upper surface of the second semiconductor die being at substantially a same height and extending substantially along a plane; and a plurality of bonding wires each coupling one of the first plurality of bond pads on the upper surface of the first semiconductor die to a corresponding one of the second plurality of bond pads on the upper surface of the second semiconductor die, a bonding wire of the plurality of bonding wires having a kink disposed at a height above the plane, the bonding wire having a first hump disposed between the first semiconductor die and the kink, and a second hump disposed between the second semiconductor die and the kink, a first height of the first hump and a second height of the second hump each being greater than the height of the kink above the plane, each bonding wire comprising: a first length extending upward from a bond pad of the second plurality of bond pads on the upper surface of the second semiconductor die to the first hump; a second length coupled to the first length at the first hump, the second length extending downward from the first hump to the kink, the kink disposed at a height above the upper surface of the first semiconductor die and the upper surface of the second semiconductor die; a third length coupled to the second length at the kink, the third length extending upward from the kink to the second hump; and a fourth length coupled to the third length at the second hump, the fourth length extending from the second hump to a bond pad of the first plurality of bond pads on the upper surface of the first semiconductor die, wherein the fourth length comprises an upper portion and a lower portion coupled at a second kink spaced from the second hump, the upper portion coupled to the third length at the second hump and extending to the second kink, and the lower portion extending from the second kink to the bond pad of the first plurality of bond pads on the upper surface of the first semiconductor die, the lower portion extending more vertically upward from the upper surface of the first semiconductor die than the upper portion, and the upper portion extending more laterally parallel to the upper surface of the first semiconductor die than the lower portion.
