Abstract:
1. A semiconductor comprising: a substrate having active circuitry; a first insulating layer over the substrate; a second insulating layer of material overlying the the first insulating layer having a cavity; a first column of metallic catalyst material through the second insulating layer and having a side exposed to the cavity on a first side of the cavity; a second column of metallic catalyst material through the second insulating layer and having a side exposed to the cavity on a second side of the cavity; a third insulating layer over the second insulating layer having an opening centered over the cavity; a first nanotube in the cavity extending from the first column to a region under the opening; and a second nanotube in the cavity extending from the second column to the region under the opening and contacting the first nanotube.
