Patent ID: 8017501

Claim:
A method of forming through-hole vias in a semiconductor wafer, comprising: forming a semiconductor wafer having a plurality of die with contact pads disposed on a surface of the plurality of die, the semiconductor wafer having a saw street between the plurality of die; cutting a trench in the saw street, the trench extending partially through the semiconductor wafer, an uncut portion of the saw street below the trench along a backside of the semiconductor wafer maintaining structural support for the semiconductor wafer during processing steps of: (a) filling the trench with an organic material, (b) forming a plurality of vias in the organic material adjacent to the contact pads, (c) depositing conductive material in the plurality of vias to form metal vias, and (d) electrically connecting the metal vias to the contact pads; removing the uncut portion of the saw street below the trench along the backside of the semiconductor wafer; and singulating the semiconductor wafer along the saw street to separate the plurality of die.
