Abstract :
We fabricated a carbon nanotube (CNT) via structure on a 300-mm wafer. We investigated the CNT chemical-mechanical polishing (CNT-CMP) behavior in an actual via pattern structure and clarified the technical issues of the CNT-CMP process. We developed a fabrication process of CNT via structures using selective CNT growth, which has a high potential for applying CNTs to high aspect ratio via structures.
