Claim Text:
1. A semiconductor die assembly, comprising: a plurality of semiconductor dice in a stack; conductive elements between and interconnecting integrated circuits of the plurality of semiconductor dice in the stack; thermally conductive structures between the plurality of semiconductor dice in the stack and electrically isolated from the integrated circuits; a dielectric material located between the plurality of semiconductor dice in the stack and around the conductive elements and the thermally conductive structures; another semiconductor die located under the plurality of semiconductor dice in the stack, the another semiconductor die comprising a relatively higher power density region within a peripheral area of the another semiconductor die extending laterally beyond the stack; and a heat dissipation structure disposed over the plurality of semiconductor dice in the stack and the another semiconductor die, the heat dissipation structure in thermal contact with an uppermost die in the stack and with the relatively higher power density region of the another semiconductor die.
