Abstract:
Vertical memory cells and memory devices using the same are disclosed. In one example, a memory cell formed on a backend layer over a substrate is disclosed. The memory cell includes: a first electrode, a second electrode and a magnetic tunnel junction. The first electrode has sidewalls and a bottom surface disposed over the backend layer. The second electrode has sidewalls and a bottom surface in contact with the backend layer. The magnetic tunnel junction is formed between the first electrode and the second electrode. The magnetic tunnel junction is coupled to a sidewall of the first electrode and coupled to a sidewall of the second electrode.

Claim (Index 18):
The method of  claim 17 , wherein removing portions of the first electrode layer, the magnetic tunnel junction layer and the second electrode layer comprises:\n etching the first electrode layer, the magnetic tunnel junction layer and the second electrode layer to form a stack cap covering the stack; forming a silicon carbide layer over the stack cap and the backend layer; forming an additional inter-metal dielectric layer over the silicon carbide layer; and polishing top portions of all layers including the stack cap on the backend layer such that the remaining portions of the first electrode layer, the magnetic tunnel junction layer and the second electrode layer adjoin the sidewall of the stack and extend along the direction perpendicular to the upper surface of the backend layer.
