Wirebond bondpads on semiconductor packages that result in reduced cross-talk and/or interference between vertical wires are disclosed. The vertical wirebonds may be disposed in the semiconductor package with stacked dies, where the wires are substantially normal to the bondpads to which the vertical wirebonds are attached on the dies. The wirebond bondpads may include signal pads that carry input/output (I/O) to/from the die package, as well as ground bondpads. The bondpads may have widths that are greater than the space between adjacent bondpads. Bondpads may be fabricated to be larger than the size requirements for reliable wirebond formation on the bondpads. For a fixed pitch bondpad configuration, the size of the signal bondpads adjacent to the ground bondpads may be greater than half of the pitch. By increasing the size of the signal bondpads adjacent to a ground line relative to the space therebetween, improved cross-talk performance may be achieved.
