Abstract:
1. A method comprising: providing a die stack having at least two stacked dies coupled for contactless communications with each other, at least one of the stacked dies having a stacked die substrate joined to a major face thereof, the stacked die substrate having a plurality of conductive traces therein for conducting power to the at least one stacked die and for conducting heat from the at least one stacked die; forming a plurality of conductive pillars on a surface of a dielectric substrate; and joining the dielectric substrate to a side edge of the die stack, with the dielectric substrate normal to the stacked die substrate, such that each of the conductive pillars makes electrical and thermal contact with a respective conductive trace in each of the at least one stacked die substrate, for conducting power to the at least one stacked die and for conducting heat from the at least one stacked die.
