Patent ID: 7271047

Claim:
A method of fabricating a test structure, comprising: forming a first conductor on a substrate, the first conductor having a first end; forming a second conductor on the substrate, the second conductor having a second end positioned above the first end of the first conductor; forming an insulating film between the first conductor and the second conductor, the insulating film having a via therein positioned between the first end of the first conductor and the second end of the second conductor; forming a third conductor positioned in the via and coupled to the first end of the first conductor and the second end of the second conductor; forming a first electrode coupled to the first conductor at a first distance from the third conductor and a second electrode coupled to the first conductor at a second distance from the third conductor; forming a third electrode coupled to the second conductor at a third distance from the third conductor and a fourth electrode coupled to the second conductor at a fourth distance from the third conductor; and wherein the first, second, third and fourth electrodes provide voltage sense taps and the first and second conductors provide current sense taps from which the resistance of the third conductor may be derived.
