Low-resistance metal contacts for CVD-nanocarbon (NC)/cobalt (Co) interconnects have been investigated among contact metals such as Ni, Ti, Au, and Cu. Contact resistivity was independent of contact area owing to low-resistance NC/Co interconnect structure. The lowest contact resistivity and superior adhesion were obtained from Ni. Although the factors for the low contact resistivity were not clear enough from the comparison of work-function difference and adhesion strength for the contact metals, Ni is a promising low-resistivity contact metal for CVD-NC interconnects in the future.
