Abstract:
1. A test structure comprising: a first conductive line; at least one insulating layer adjacent the first conductive line; a via formed in a contact hole in the at least one insulating layer, the via being electrically coupled to the first conductive line; a second conductive line disposed in a plane of the first conductive line, the second conductive line extending parallel to a first edge of the first conductive line, extending around the via, and extending parallel to a second edge of the first conductive line, wherein the first edge is opposed to the second edge; and a third conductive line disposed in the plane of the first conductive line, the third conductive line extending parallel to the first edge of the first conductive line, extending around the via, and extending parallel to the second edge of the first conductive line such that the second conductive line is disposed between the first conductive line and the third conductive line.
