Semiconductor wafer level interconnect package utilizing conductive ring and pad for separate voltage supplies and method of making the same

Abstract

A semiconductor die has active circuits formed on its active surface. Contact pads are formed on the active surface of the semiconductor die and coupled to the active circuits. A die extension region is formed around a periphery of the semiconductor die. Through hole vias (THV) are formed in the die extension region. A conductive plane or ring is formed in a center area on the active surface of the semiconductor die. The conductive plane or ring is coupled to a first contact pad for providing a first power supply potential to the active circuits. The conductive plane or ring is electrically connected to a first THV. A conductive ring is formed partially around a perimeter of the conduction plane or ring. The conductive ring is coupled to a second contact pad for providing a second power supply potential to the active circuits. The conductive ring is electrically connected to a second THV.
