Abstract: A memory cell and a method of making the same, that includes insulating material deposited on a substrate, a bottom electrode formed within the insulating material, a plurality of insulating layers deposited above the bottom electrode and at least one of which acts as an intermediate insulating layer. A via is defined in the insulating layers above the intermediate insulating layer. A channel is created for etch with a sacrificial spacer. A pore is defined in the intermediate insulating layer. All insulating layers above the intermediate insulating layer are removed, and the entirety of the remaining pore is filled with phase change material. An upper electrode is formed above the phase change material.
