Abstract

Electrical connection in an integrated circuit arrangement is facilitated with carbon nanotubes. According to various example embodiments, a carbon nanotube material ( 120, 135 ) is associated with another material ( 130, 125 ) such as a metal. The carbon nanotube material facilitates the electrical connection between different circuit components.
