- Future miniaturization of advanced electronic systems will require 3D chip-to-chip stacking of high performance processor chips. Such systems raise a number of questions concerning power distribution and thermal management issues. Efficient through-silicon-via (TSV) technology and new thermal interface materials will be required for such systems to be successful. Carbon nanotubes (CNT) have been suggested as a candidate material with good mechanical properties, and good thermal and electrical conductivities superior to those of copper TSVs. In this paper we will describe our efforts on producing through-silicon-vias based on carbon nanotube bundles grown from the bottom of 150 m deep silicon vias with 50*50 µm openings. The resistances of such CNT vias have been electrically measured and found to be about 2.0 kΩ, a result very close to previously reported values. However, these values are orders of magnitude too high for practical use and not at all close to values reported from measurements on short carbon nanotubes. New processes are suggested too improve growth of long CNTs.
