Semiconductor device with a layered protection mechanism and associated systems, devices, and methods

Abstract:

A semiconductor device includes a first die; a second die attached over the first die; a metal enclosure directly contacting and extending between the first die and the second die, wherein the first metal enclosure is continuous and encircles a set of one or more internal interconnects, wherein the first metal enclosure is configured to electrically connect to a first voltage level; and a second metal enclosure directly contacting and extending between the first die and the second die, wherein the second metal enclosure is continuous and encircles the first metal enclosure and is configured to electrically connect to a second voltage level; wherein the first metal enclosure and the second metal enclosure are configured to provide an enclosure capacitance encircling the set of one or more internal interconnects for shielding signals on the set of one or more internal interconnects.
