Abstract

Official abstract text for this publication.

A phase change memory cell and a method for fabricating the phase change memory cell. The phase change memory cell includes a bottom electrode and a first non-conductive layer. The first non-conductive layer defines a first well, a first electrically conductive liner lines the first well, and the first well is filled with a phase change material in the phase change memory cell.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for fabricating a phase change memory cell, the method comprising: forming a bottom electrode; depositing a first non-conductive layer above the bottom electrode; defining a first well in the first non-conductive layer that is positioned directly above the bottom electrode; lining a first electrically conductive liner along at least one wall of the first well such that the first electrically conductive liner partially fills the first well and…
