Clip structure and semiconductor package using the same

Abstract

A clip structure and a semiconductor package using the same include different metals in multiple layers so as to selectively, easily and exactly fix semiconductor chips, which consists of a lightweight material so as to lighten the weight of semiconductor packages and to help reduce manufacturing costs, and which in particular, maintains the width of a self-welding layer consisting of a clip structure so as to help improve the quality of adhesion. That is, according to a clip structure of the present invention, which electrically connects package elements in a semiconductor package, the clip structure includes a main metallic layer that is configured to maintain a shape, and a first functional layer that is piled on one surface of the main metallic layer and consists of a metal different from that of the main metal layer.
