A new characterization of sub-/spl mu/m parallel multilevel interconnects and its experimental verification

Abstract

This paper describes a new interconnect design and its verification with test-structures for sub-micron multilevel interconnection. A universal design-chart has been developed, which gives a precise sub-micron interconnect-capacitance for parallel multilevel interconnections. Test-structure measurements show excellent agreement with the design-chart within 4% error. A simple propagation delay model has also been developed.
