We report the present status of Carbon Nanotube (CNT) CVD material technologies and their applications for via interconnects and FETs for VLSI. We succeeded in growing multi-walled CNTs (MWNTs) with the highest shell density (as high as 1013/cm2) and in fabricating via interconnects with high robustness against a high current density. We also report a Si-process compatible technique to control carrier polarity of Single-walled CNT (SWNT) FETs by utilizing fixed charges introduced by the gate oxide. High-performance p- and n-type CNT-FETs and CMOS inverters with stability in air have been realized.
