Abstract:
1. A method of making a semiconductor device, comprising: providing a semiconductor wafer having a plurality of semiconductor die, each semiconductor die having a contact pad formed on a front side of the die; creating a gap between the semiconductor die; depositing an insulating material in the gap; removing a portion of the insulating material to form a via; depositing conductive material in the via to form a conductive via; forming a conductive layer between the conductive via and contact pad on the semiconductor die; forming a protective layer over the front side of the semiconductor die; removing a portion of the insulating material and conductive via from a backside of the semiconductor die opposite the front side of the semiconductor die so that a thickness of the conductive via is less than a thickness of the semiconductor wafer; and singulating the semiconductor wafer through the gap to separate the semiconductor die.
