Abstract:
Processing methods comprising selectively replacing a first pillar material with a second pillar material in a self-aligned process are described. The first pillar material may be grown orthogonally to the substrate surface and replaced with a second pillar material to leave a substantially similar shape and alignment as the first pillar material.
