CN104584250A 包括磁各向异性增强层和结晶阻碍层的垂直MTJ堆叠体 失效 - 权利终止

包括磁各向异性增强层和结晶阻碍层的垂直MTJ堆叠体
Abstract:
本发明描述了适用于自旋转移矩存储器(STTM)器件的磁性隧道结(MTJ)，其包括垂直磁层、以及由结晶阻碍层而与自由磁层分开的一个或多个各向异性增强层。在实施例中，各向异性增强层改善所述自由磁层的垂直取向，而结晶障碍利用所述自由磁层的晶体织构与隧穿层的晶体织构的更好的对准来改善隧道磁致电阻(TMR)比。
Abstract(English):

Magnetic tunnel junctions (MTJ) suitable for spin transfer torque memory (STTM) devices, include perpendicular magnetic layers and one or more anisotropy enhancing layer(s) separated from a free magnetic layer by a crystallization barrier layer. In embodiments, an anisotropy enhancing layer improves perpendicular orientation of the free magnetic layer while the crystallization barrier improves tunnel magnetoresistance (TMR) ratio with better alignment of crystalline texture of the free magnetic layer with that of a tunneling layer.
