Abstract
The chip stack of semiconductor chips with enhanced cooling apparatus includes a first chip with circuitry on a first side and a second chip electrically and mechanically coupled to the first chip by a grid of connectors. The chip stack further includes a thermal interface material pad between the first chip and the second chip. The thermal interface material pad comprises a plurality of nanotubes containing a magnetic material, aligned parallel to mating surfaces of the first chip and the second chip, wherein a hydrophobic tail of oleic acid is wrapped around each one of the plurality of nanotubes and a hydrophilic acid head of the oleic acid is attached to the magnetic material.
