Maximum current density, thin film


For LSI layout calculations I am looking for the maximum current density of thin film aluminum, chromium and gold.

I guess it is a Foundry parameter but I need some rough number.

Could you help?

The current density is limited by electromigration effects and is limited to the order of mega-amp/cm.sq. cross-section area of the interconnect. These standards have been established in the industry and should be available in semiconductor electronics literature or even Journal of Electrochemical Society.
