85

One type of die stack is a staircase stack. In a staircase stack, the dies may be stacked on top of one another such that the dies do not completely cover each other. Instead, each die has an exposed portion where respective I/O contact pads may be disposed and connected with each other via wire bonds. By disposing the dies on top of one another to create exposed portions, the dies of the die stack, when viewed from the side, have a "staircase" shape, which each die being one of the "steps" of the staircase.
