CONDUCTIVE STRUCTURE OF A CHIP AND METHOD FOR MANUFACTURING THE SAME

摘要

A conductive structure of a chip and a method for manufacturing the conductive structure are provided. An under bump metal (UBM) is formed on the redistribution layer (RDL) by performing an electroless plating process. Subsequently, the solder bump is formed on the under bump metal for electrical connection. Thus, the photomask can be economized and the cost of manufacturing can be reduced.
