Abstract: In an embodiment, a thermal interface material (TIM) is provided. The TIM comprises first and a second layers of a first transition metal, and a third layer including a plurality of carbon nanotubes supported in a flexible polymer matrix and a second transition metal coupled to sidewalls of carbon nanotubes. The first and second metal layers are in contact with first and second ends of carbon nanotube. The TIM further comprises fourth and fifth layers of an alloy material coupled to the first and second metal layers, respectively. The carbon nanotube based TIM including the layers with transition metal allow improved heat transfer from an integrated circuit die to a heat spreader.
