Abstract: A method for making a semiconductor device includes forming rims on first and second dice. The rims extend laterally away from the first and second dice. The second die is stacked over the first die, and one or more vias are drilled through the rims after stacking. The semiconductor device includes redistribution layers extending over at least one of the respective first and second dice and the corresponding rims. The one or more vias extend through the corresponding rims, and the one or more vias are in communication with the first and second dice through the rims.
