Abstract

A method of forming air gaps within a solid structure is provided. In this method, a sacrificial material is covered by an overlayer. The sacrificial material is then removed through the overlayer to leave an air gap. Such air gaps are particularly useful as insulation between metal lines in an electronic device such as an electrical interconnect structure. Structures containing air gaps are also provided.
