Jt. Trattles et al., 3-DIMENSIONAL FINITE-ELEMENT INVESTIGATION OF CURRENT CROWDING AND PEAK TEMPERATURES IN VLSI MULTILEVEL INTERCONNECTIONS, I.E.E.E. transactions on electron devices, 40(7), 1993, pp. 1344-1347
Multilevel interconnection vias are investigated with a coupled therma
l and electrical conduction model in three dimensions using the finite
-element method. The concept of using a volume to quanitfy current cro
wding is introduced. Close to a contact via it is found that the peak
temperature moves between the upper track and the via as a function of
geometry.
