Patent ID: 8604618

Claim:
A semiconductor device comprising: an insulator; and a plurality of vertically stacked layers on said insulator, each of said vertically stacked layers including: a first dielectric insulator portion; a first conductor within said first dielectric insulator portion; a first nitride cap covering said first conductor; a second dielectric insulator portion; a second conductor within said second dielectric insulator portion; and a second nitride cap covering said second conductor, said first conductor within said vertically stacked layers forming first vertically stacked conductor layers, said second conductor within said vertically stacked layers forming second vertically stacked conductor layers, said first vertically stacked conductor layers being proximate said second vertically stacked conductor layers, and said vertically stacked layers further comprising an air gap positioned between said first vertically stacked conductor layers and said second vertically stacked conductor layers of said semiconductor device.
