Abstract: According to one aspect of the invention, a method of constructing an electronic assembly is provided. A layer of metal is formed on a backside of a semiconductor wafer having integrated formed thereon. Then, a porous layer is formed on the metal layer. A barrier layer of the porous layer at the bottom of the pores is thinned down. Then, a catalyst is deposited at the bottom of the pores. Carbon nanotubes are then grown in the pores. Another layer of metal is then formed over the porous layer and the carbon nanotubes. The semiconductor wafer is then separated into microelectronic dies. The dies are bonded to a semiconductor substrate, a heat spreader is placed on top of the die, and a semiconductor package resulting from such assembly is sealed. A thermal interface is formed on the top of the heat spreader. Then a heat sink is placed on top of the thermal interface.

Fabrication apparatus and methods, as well as application of the imprinted package to an electronic assembly, are also described.

Other embodiments are described and claimed.

Abstract: A carbon nanotube (CNT) array is patterned on a substrate. The substrate can be a microelectronic die or a heat sink for a die. The patterned CNT array is patterned by using a patterned catalyst on the substrate to form the CNT array by growing. The patterned CNT array can also be patterned by using a patterned mask on the substrate to form the CNT array by growing. A computing system that uses the CNT array for heat transfer from the die is also used.
