Abstract
A simple, accurate method of measuring interconnect capacitances is presented. The test structure has excellent resolution, needs only DC measurements, and is compact enough for scribe-line implementation. These qualities make it suitable for measurement-based, interconnect capacitance characterization in a comparable fashion to current characterization efforts for MOSFET devices. The entire characterization scheme is demonstrated for a production 0.5 /spl mu/m, three-level metal technology. The method not only provides an accurate assessment of actual capacitance variation but provides valuable feedback on the variability of physical parameters such as interlevel dielectric (ILD) thickness and drawn width reductions for process control as well.
