Abstract
Mitigation of detrimental mobile ion contamination effects in integrated circuits (ICs) using a metal with a negative voltage bias or connected to a negative voltage source supply (−VSS) is disclosed. Such architectures mitigate mobile ion contamination by selecting/imposing advantageous layout geometries/rules within upon the device structure, bias voltages, and/or multi-level interconnects present in the IC design. More specifically, safe routing of a positive voltage in a metal trace crossing/spanning multiple resistors or transistors is provided.
