Abstract:
A first etch stop layer is deposited on a plurality of conductive features on an insulating layer on a substrate. A second etch stop layer is deposited over an air gap between the conductive features. The first etch stop layer is etched to form a via to at least one of the conductive features.

Claim (Index 9):
A method to provide a maskless air gap process, comprising:\n curing a first sacrificial layer on a plurality of conductive features on an insulating layer on a substrate to align a first material of the first sacrificial layer to first portions of the insulating layer between the conductive features and to align a second material of the first sacrificial layer to the plurality of conductive features; etching the first material to expose the first portions of the insulating layer; depositing a second sacrificial layer onto the exposed first portions of the insulating layer; removing the second material layer to expose portions of the conductive features; depositing a first etch stop layer one the exposed portions of the conductive features; and forming an air gap between at least two of the conductive features.
