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.

摘要: A conductive structure of a chip is provided. The conductive structure comprises a ground layer, a dielectric layer, a redistribution layer, an under bump metal and a solder bump. The ground layer electrically connects to the ground pad of the chip, while the dielectric layer overlays the ground layer. Thus, the conductive layer can result in impedance matching, and the packaged chip is adapted to transmit a high frequency signal.
