Patent ID: 7187179

Claim:
A wiring test structure, comprising: a plurality of wiring traces configured in a spiral pattern, with at least one of said plurality of wiring traces configured for open circuit testing therein, and at least a pair of said plurality of wiring traces configured for short circuit testing therebetween; a first wiring plane containing said plurality of spiral pattern traces; a second wiring plane having at least one conductive trace connected to at least one of said plurality of spiral pattern traces through at least one via; a first wiring path, said first wiring path including a first probe pad within said first wiring plane, a first of said spiral pattern traces, a first via, a first conductive trace in said second wiring plane, and a third probe pad in said second wiring plane; and a second wiring path, said second wiring path including a second probe pad within said first wiring plane, a second of said spiral pattern traces, a second via, a second conductive trace in said second wiring plane, and a fourth probe pad in said second wiring plane.
