Abstract:
A magnetoresistive random access memory (MRAM) structure includes a bottom electrode structure. A magnetic tunnel junction (MTJ) element is over the bottom electrode structure. The MTJ element includes an anti-ferromagnetic material layer. A ferromagnetic pinned layer is over the anti-ferromagnetic material layer. A tunneling layer is over the ferromagnetic pinned layer. A ferromagnetic free layer is over the tunneling layer. The ferromagnetic free layer has a first portion and a demagnetized second portion. The MRAM also includes a top electrode structure over the first portion.

Claim (Index 1):
A method comprising:\n providing a magnetoresistive random access memory (MRAM) structure comprising:\n an anti-ferromagnetic material layer; \n a pinned layer over the anti-ferromagnetic material layer; \n a tunneling layer over the pinned layer; \n a ferromagnetic free layer over the tunneling layer, the ferromagnetic free layer having a first portion and a second portion; and \n a first electrode layer over the ferromagnetic free layer; \n patterning the first electrode layer to expose the second portion of the ferromagnetic free layer, remaining portions of the first electrode layer on the first portion of the ferromagnetic free layer forming a first electrode structure; treating the second portion of the ferromagnetic free layer to demagnetize the second portion of the ferromagnetic free layer; forming protection spacers on the second portion of the ferromagnetic free layer; and patterning the ferromagnetic free layer, the tunneling layer, the pinned layer, and the anti-ferromagnetic material layer using the protection spacers and the first electrode structure as an etch mask.
