Abstract:
1. A test semiconductor device comprising: a test structure constructed in said semiconductor device, said test structure comprising a first conductive metal structure having a first test function for accepting a flow of electric current that causes a heating effect, and a second conductive metal structure proximate said first conductive structure having a second test function for exhibiting resistivity changes in response to said heating effect, wherein the respective first and second test functions for the first and second conductive metal structures are mutually interchangeable with one another, wherein said first and second conductive metal structures comprise electrically separate structures from one another, wherein said device comprises a multi-level semiconductor device, and further wherein said multi-level device includes respective ones of said first and second conductive metal structures at each level of said device for determining a respective heating effect at each individual level, and wherein one of said conductive metal structures comprises a series of interconnect lines electrically connected to one another throughout said multi-level device by way of a chain of stacked vias.
