Abstract:
First stacked rail structures including a first conductive rail, a selector rail, and a sacrificial material rail and separated by first trenches are formed over a substrate. First dielectric isolation structures are formed in the first trenches. Second trenches are formed, which divides the first stacked rail structures above the first conductive rails. Second dielectric isolation structures in the second trenches. Pillar structures are formed, which include a respective vertical stack of a selector element and a sacrificial material pillar. The sacrificial material pillars are replaced with phase change memory material pillars by a damascene method that deposits and planarizes a phase change memory material. Second conductive rails are formed over the phase change memory material pillars. Sidewalls of the phase change memory material pillars are not subjected to etch damage, thereby enhancing electrical characteristics of the phase change memory material pillars.

Claim (Index 2):
The method of  claim 14 , wherein:\n the first selector element comprises a chalcogenide ovonic threshold switch material; and the first phase change memory material is selected from germanium antimony telluride compounds, germanium antimony compounds, indium germanium telluride compounds, aluminum selenium telluride compounds, indium selenium telluride compounds, and aluminum indium selenium telluride compounds.
