Abstract:
1. A system for altering a wiring path of a stacked chip structure, the wiring path including a through-silicon via (TSV), the system comprising: an electrical testing machine configured to measure an electrical resistance of the wiring path; a power supply configured to supply a voltage in a range of 100 volts to 500 volts; an insulating fixture configured to support the stacked chip structure; a field charging electrode in the insulating fixture and electrically coupled with the power supply, the field charging electrode configured to be selectively charged by the power supply to the voltage; and a controller coupled with the electrical testing machine and with the power supply, the controller configured to receive the electrical resistance from the electrical testing machine, to compare the electrical resistance with a reference range of electrical resistances, and to cause the power supply and the field charging electrode to capacitively charge the stacked chip structure to the voltage if the electrical resistance is within the reference range of resistance values.
