Abstract

A connecting element for electrically connecting a semiconductor chip and a superordinate circuit board includes an elastic metal strip that is bent forming two metal limbs with flattened limb ends, thus forming a base between the metal limbs which is suitable for contacting and providing electrical connectivity to a plurality of contact pads of a superordinate circuit board. At least one of the two limb ends is electrically connected to the contact areas of a semiconductor chip, while the other limb end is elastically supported on the top side of the semiconductor chip, thereby enabling the connecting element to be self supporting.
