Claim Text:
1. A method of making a semiconductor device, comprising: providing a semiconductor wafer including a plurality of semiconductor die with a plurality of contact pads formed over an active surface of the semiconductor die; forming a first opening into the active surface of the semiconductor die with the first opening extending partially through the semiconductor wafer; forming a second opening into a saw street in an inactive area of the semiconductor wafer between the semiconductor die with the second opening extending partially through the semiconductor wafer; forming a conductive layer over the active surface of the semiconductor die and into the first opening and second opening to operate as a shielding layer extending over the active surface, into the first opening, and around side surfaces of the semiconductor die; and removing a portion of the semiconductor wafer opposite the active surface of the semiconductor die, wherein after removing the portion of the semiconductor wafer the first opening extends from the active surface of the semiconductor die through the semiconductor die to reach a second surface of the semiconductor die opposite the active surface of the semiconductor die.
