    Abstract: Aspects of the present disclosure provide an integrated circuit (IC) test structure. An IC structure according to the present disclosure can include: a monitor chain having a first end electrically connected to a second end through a plurality of metal wires each positioned within one of a first metal level and a second metal level, wherein the first metal level is vertically separated from the second metal level; a first test wire positioned within the first metal level and extending in a first direction, wherein the first test wire is electrically insulated from the monitor chain; and a second test wire positioned within the second metal level and extending in a second direction, wherein the second test wire is electrically insulated from the monitor chain and the first test wire, and wherein the first direction is different from the second direction.
