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 11):
A magnetoresistive memory device, comprising:\n a magnetoresistive cell disposed on a lower electrode; and an upper electrode disposed on the magnetoresistive cell, wherein the magnetoresistive cell comprises: a ferromagnetic layer; a tunneling barrier layer disposed on the ferromagnetic layer; a free magnetic layer disposed on the tunneling barrier layer; an oxide layer including boron (B) and disposed on the free magnetic layer; and a capping layer disposed on the oxide layer, and wherein the free magnetic layer has a gradually gradated concentration of boron (B) from a lower portion having a relatively low concentration of boron (B) to an upper portion having a relatively high concentration of boron (B).
