发明名称 PACKAGING STRUCTURE AND METHOD FOR FABRICATING THE SAME
摘要 The present invention provides a packaging structure and a method for fabricating the same, the packaging structure includes a chip, a compatible pad provided on the chip, an intermediate metal layer electrically connecting with the compatible pad, a solder bump, and a redistribution metal layer electrically connecting with the solder bump, wherein the redistribution metal layer connects with the intermediate metal layer directly to form an electrical connection. Also, some connections between the redistribution metal layer and the intermediate metal layer are in a manner of concave shape, while other connections between the redistribution metal layer and the intermediate metal layer are in a manner of "-" shape, so that the number of the connections increases while the stability of connection is ensured.
