## Re: How to calculate current density formula?

Current density is always I/A. The question is, what

is your true linewidth and your true film thickness at

the worst case feature (and where is it)? And you get

repeat that for every metal layer.

Most foundries give you simple mA/um or mA/contact

rules to follow, which would embody the deltaL, deltaT

effects.
