Abstract
A contact clip, primarily for use in semiconductor devices comprises a layer of material having a relatively high coefficient of thermal expansion and another layer of relatively low coefficient of thermal expansion. Such a clip improves the contact between the clip and the semiconductor pellet to which it is soldered not only during device assembly but also at high operating temperatures as well.
