Dear Tosei,
Yes, I know that formula. I was confused with the unit Ωcm because I focused on the '1/L' term. But together with the 'A' term you end up indeed with a single dimension, thus indeed cm.
Given that number, how can you proceed to have an estimate of resistivity between 2 points on a die? You could just measure the distance I guess and apply the above formula, but since you have several parallel paths... Maybe it's just too complicated to estimate by hand.
Regards
Peter
