    摘要: A method for determining the electromigration characteristics of a wiring structure in an integrated circuit device is disclosed. In an exemplary embodiment of the invention, the method includes configuring a defined test structure type for the integrated circuit device. The defined test structure type further includes a first line of wiring primarily disposed in a principal plane of a semiconductor substrate, and a second line of wiring connected to the first line of wiring. The second line of wiring is disposed in a secondary plane which is substantially parallel to the principal plane, with the first and second lines of wiring being connected by a via structure therebetween. A thermal coefficient of resistance for the first line of wiring and the via structure is determined, and a wafer-level stress condition is introduced in a first individual test structure of the defined test structure type. Then, at least one parameter value for is determined for the first individual test structure, which parameter value is used to predict a lifetime projection for the wiring structure in the integrated circuit device.

    摘要: A test circuit for testing semiconductors includes a plurality of at least first conductors and second conductors. The first and second conductors are operatively connected together by a plurality of conductive vias to form an open chain of alternating first and second conductors. A plurality of conductive taps are included, each of the taps being connected at a first end to a corresponding first conductor. The test circuit further includes a plurality of switching circuits, each of the switching circuits being operatively connected to a second end of a corresponding one of the conductive taps. Each of the switching circuits is configurable for selectively connecting the corresponding conductive tap to one of at least a first bus and a second bus in response to at least one control signal presented to the switching circuit, the first and second buses being connected to first and second bond pads, respectively.
