A multiple die structure includes a first die (110), a second die (120), a carbon nanotube (130) having a first end (131) in physical contact with the first die and having a second end (132) in physical contact with the second die, and an electrically conductive material (240) in physical contact with the first end of the carbon nanotube and in physical contact with the first die. Forming a connection between the first die and the second die can include providing a connection structure (400, 500, 600, 900) in which the electrically conductive material is adjacent to the carbon nanotube, placing the connection structure adjacent to the first die and to the second die, and bonding the first die and the second die to the connection structure.
