Abstract
Self-aligned semiconductor device structures and techniques for fabrication thereof are provided. In one aspect, a self-aligned semiconductor device structure includes: at least one first conductive element embedded in a first dielectric; a second dielectric disposed selectively on the first dielectric relative to the at least one first conductive element; and at least one second conductive element present in the second dielectric that is fully aligned with the at least one first conductive element. A liner can be disposed on the second dielectric and which separates the second dielectric from the at least one second conductive element. A method of forming a self-aligned semiconductor device structure is also provided.
