Methods of forming self-aligned vias and air gaps |
abstract |
A first metallization layer comprises a set of first conductive lines that extend along a first direction on a first dielectric layer on a substrate. Pillars are formed on recessed first dielectric layers and a second dielectric layer covers the pillars. A dual damascene etch provides a contact hole through the second dielectric layer and an etch removes the pillars to form air gaps. |
