ABSTRACT:
Disclosed are semiconductor dice with backside trenches filled with elastic conductive material. The trenches reduce the on-state resistances of the devices incorporated on the dice. The elastic conductive material provides a conductive path to the backsides of the die with little induced stress on the semiconductor die caused by thermal cycling. Also disclosed are packages using the dice, and methods of making the dice.
