a base material;
at least one metal pad,
wherein a first surface of the metal pad is in contact with a surface of the base material;
a metal pedestal;
wherein a first surface of the metal pedestal is in contact with a second surface of the metal pad,
wherein the metal pad has a cross section that, when viewed in a top-down view, is an elliptical shape, and
wherein an axis running through a shortest diameter of the metal pad is perpendicular to a line running from the center of the metal pad to the center of the base material; and
a solder bump in contact with a second surface of the metal pedestal.
