Abstract

A semiconductor structure forms two or more tightly pitched memory devices using a dielectric material for a gap fill material. The approach includes providing two adjacent bottom electrodes in a layer of an insulating material and above a metal layer. Two adjacent pillars are each above one of the two adjacent bottom electrodes where each pillar of the two adjacent pillars is composed of a stack of materials for a memory device. A spacer is around the vertical sides each of the two adjacent pillars. The dielectric material is on the spacer around the vertical sides each of the two adjacent pillars, on the layer of the insulating material between the two adjacent bottom electrodes. The dielectric material fills at least a first portion of a gap between the two adjacent pillars. A low k material covers the dielectric material and exposed portions of the layer of the insulating material.
