Abstract:
MTJ material stacks with a laterally strained free magnetic layer, STTM devices employing such stacks, and computing platforms employing such STTM devices. In some embodiments, perpendicular pMTJ material stacks included free magnetic layers that are compressively strained laterally by a surrounding material, which increases coercive field strength for a more stable device. In some embodiments, a pMTJ material stack is encased in a compressive-stressed material. In some further embodiments, a pMTJ material stack is encased first in a dielectric shell, permitting a conductive material to be deposited over the shell as the compressive-stressed, strain-inducing material layer.

Claim (Index 34):
A method of forming a perpendicular magnetic tunneling junction (pMTJ) device, the method comprising:\n depositing a pMTJ material stack over a substrate, the pMTJ material stack including a tunnel dielectric material layer between a fixed magnetic material layer and a free magnetic material layer, both the fixed and free magnetic material layers having perpendicular magnetic anisotropy; patterning the pMTJ material stack into an array of discrete pMTJ structures disposed over the substrate; depositing a compressive-stressed material over the array, the compressive-stressed material covering a sidewall of at least the free magnetic layer; planarizing the compressive-stressed material with the array of pMTJ structures to expose a plurality of pMTJ electrodes; and interconnecting the pMTJ electrodes.
