Abstract
The present invention provides a structure. In an exemplary embodiment, the structure includes a base material, at least one metal pad, where a first surface of the metal pad is in contact with the base material, and a metal pedestal, where the metal pedestal is in contact with the metal pad, where a radial alignment of the metal pad is shifted by an offset distance, with respect to the metal pedestal, such that the metal pad is shifted towards a center axis of the base material, where a first dimension of the metal pad is smaller than a second dimension of the metal pad, where the second dimension is orthogonal to a line running from a center of the metal pad to the center axis of the base material, where the first dimension is parallel to the line.
