Abstract
Official abstract text for this publication.
A device is disclosed. The device includes a top electrode, a bottom electrode and a storage element between the top and bottom electrodes. The storage element includes a heat generating element disposed on the bottom electrode, a phase change element wrapping around an upper portion of the heat generating element, and a dielectric liner sandwiched between the phase change element and the heat generating element.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming a device comprising: providing a bottom electrode; forming a storage element over the bottom electrode, wherein the storage element comprises a heat generating element directly disposed on the bottom electrode, a phase change stack which comprises at least a phase change layer and a dielectric liner, wherein the phase change layer wraps around an upper portion of the heat generating element and the dielectric liner wraps around the s…
