Abstract
A via is formed on a wafer to lie within an opening in a non-conductive structure and make an electrical connection with an underlying conductive structure so that the entire top surface of the via is substantially planar, and lies substantially in the same plane as the top surface of the non-conductive structure. The substantially planar top surface of the via enables a carbon nanotube switch to be predictably and reliably closed.
