Patent ID: 7668004

Claim:
A structure, comprising: a first insulating layer on a top surface of a substrate; an electrically conductive bitline on a top surface of said first insulating layer; a second insulating layer on a top surface of said bitline, a region of said top surface of said bitline exposed in an opening in said second insulating layer; a electrically conductive first wordline formed on a top surface of said second insulating layer, a dielectric first spacer on a sidewall of said first wordline and a dielectric second spacer on said first spacer, said first and second spacers intervening between said first wordline and said opening; a electrically conductive second wordline formed on said top surface of said second insulating layer and a dielectric third spacer on a sidewall of said second wordline, said third spacer intervening between said second wordline and said opening; and at least one electrically conductive nanotube having a first end permanently attached to said top surface of said bitline in said opening.
