Abstract:
A method of forming a magnetoresistive memory device includes forming a ferromagnetic layer, forming a tunneling barrier layer on the ferromagnetic layer, forming a first preliminary free magnetic layer (free layer) containing boron (B) on the tunneling barrier layer, forming a first buffer layer on the first preliminary free layer, performing a first annealing process to transition the first preliminary free layer to form a second preliminary free layer and the first buffer layer to form a first boride layer, performing an etching process to remove the first boride layer, forming a second buffer layer on the second preliminary free layer, performing a second annealing process to transition the second preliminary free layer to form a free layer and the second buffer layer to form a second boride layer, and performing an oxidation process to transition the second boride layer to an oxide layer.

Claim (Index 16):
A magnetoresistive memory cell, comprising\n a ferromagnetic layer, the ferromagnetic layer comprising a first surface and a second surface that is opposite the first surface of the ferromagnetic layer; a tunnel barrier layer on the ferromagnetic layer, the tunnel barrier comprising a first surface and a second surface that is opposite the first surface of the tunnel barrier layer, the first surface of the tunnel barrier layer being proximate to the second surface of the ferromagnetic layer; and a free magnetic layer on the tunnel barrier layer, the free magnetic layer comprising a first surface and a second surface that is opposite the first surface of the free magnetic layer, the first surface of the free magnetic layer being proximate to the second surface of the tunnel barrier layer, the free magnetic layer further comprising a first region that is proximate to the second surface of the tunnel barrier layer and a second region that is distal to the second surface of the tunnel barrier layer, and the first region comprising a concentration of boron that is less that a concentration of boron of the second region.
