Magnetic tunnel junction (MTJ) to reduce spin transfer magnetization switching current |
| abstract |
A MTJ that minimizes spin-transfer magnetization switching current (Jc) in a Spin-RAM to <1×10 6 A/cm 2 is disclosed. The MTJ has a Co 60 Fe 20 B 20 /MgO/Co 60 Fe 20 B 20 configuration where the CoFeB AP1 pinned and free layers are amorphous and the crystalline MgO tunnel barrier is formed by a ROX or NOX process. The capping layer preferably is a Hf/Ru composite where the lower Hf layer serves as an excellent oxygen getter material to reduce the magnetic “dead layer” at the free layer/capping layer interface and thereby increase dR/R, and lower He and Jc. The annealing temperature is lowered to about 280° C. to give a smoother CoFeB/MgO interface and a smaller offset field than with a 350° C. annealing. In a second embodiment, the AP1 layer has a CoFeB/CoFe configuration wherein the lower CoFeB layer is amorphous and the upper CoFe layer is crystalline to further improve dR/R and lower RA to ≦10 ohm/μm 2 . |
