Claim 6:
7. A microelectronic device assembly, comprising:
a stack of microelectronic devices over a substrate segment extending laterally beyond sides of the stack of microelectronic devices;
one or more metal heat transfer structures on a surface of the substrate segment and at least adjacent to one or more sides of the stack of microelectronic devices,
the one or more metal heat transfer structures electrically isolated from circuits of the microelectronic devices of the stack and of the substrate segment,
an uppermost surface of the one or more metal heat transfer structures positioned vertically below a lowermost surface of a lowermost one of the microelectronic devices of the stack, and wherein at least one of the one or more heat transfer structures extends into a street area of the substrate segment adjacent a respective location;

a dielectric encapsulant material at least extending over sides of the stack of microelectronic devices and contacting the surface of the substrate segment; and
conductive elements vertically between the surface of the substrate segment and the lowermost surface of the lowermost one of the microelectronic devices of the stack.
