Structural and electrical characterization of carbon nanotube interconnects by combined transmission electron microscopy and scanning spreading resistance microscopy KU Leuven
The use of carbon nanotubes (CNT) as interconnects in future integrated circuits (IC) is being considered as a replacement for copper. As this research needs also innovative metrology solutions, we have developed a combined approach for the plane-view analysis of CNT integrated in contact holes where transmission electron microscopy (TEM) enables the quantitative measurement of density and structure of the CNT and where scanning spreading ...
