Patent ID: 8828749

Claim:
A method for evaluating the electrical characteristics of carbon nanotubes comprising: a. growing carbon nanotubes directly on a substrate consisting of a silicon wafer and a dielectric film coating, wherein the dielectric film comprises at least one member selected from the group consisting of NiPtSi, CoSi and TiN and the carbon nanotubes are permanently affixed to the substrate; b. filling the gap around the carbon nanotubes with a polymeric fill matrix comprising at least one latent photoacid generator wherein the polymeric fill matrix has an index of refraction (n) of about 1.45 to about 2.1 and an extinction coefficient of about 0.01 to about 0.6 at 365, 248, 193 and 157 nm; c. selectively etching-back the polymeric fill matrix to expose tips of the carbon nanotubes; d. curing the polymeric fill matrix; e. depositing a layer of photosensitive dielectric material onto the cured polymeric fill matrix; f. forming an interconnect pattern with at least one opening in the layer of photosensitive dielectric material with lithography; g. filling the interconnect pattern with an electrically conductive material; and h. evaluating the electrical characteristic of the carbon nanotubes, which are attached to the substrate, after filling the interconnect pattern with an electrically conductive material.
