Abstract:
Methods of forming a pillar contact extension within a memory device using a self-aligned planarization process rather than direct ILD CMP and the resulting devices are provided. Embodiments include forming a photoresist layer over a low-K layer formed over an ILD having a first metal layer in a memory region and in a logic region and pillar-shaped conductors formed atop of the first metal layer only in the memory region; forming a trench through the photoresist layer over each pillar-shaped conductor; extending the trench through the low-K layer to an upper surface of each pillar-shaped conductor; forming a second metal layer over the low-K layer, filling the trench entirely; and planarizing the second metal layer until the second metal layer is removed from over the logic region, a pillar contact extension formed atop of each pillar-shaped conductor.

Claim (Index 16):
The device according to  claim 8 , further comprising:\n a second low-K layer over the low-K layer and pillar contact extensions; and a BEOL contact at least atop of each pillar contact extension in the memory region and the metal layer in the logic region and through the second low-K layer and the first low-K layer, respectively.
