Inventor: JIAN HONG
IPC: H01L43/12
Filed: 2020-12-31
Abstract: An MTJ manufacturing method and an MTJ. The manufacturing method comprises: sequentially forming and stacking together a reference layer (50), an insulating barrier layer (40), and a free layer (30), wherein at least one of the reference layer (50) and the free layer (30) is formed via physical vapor deposition, and at least one of xenon and krypton is used as a sputtering gas in a process of forming, via physical vapor deposition, at least one magnetic layer in the reference layer (50) and the free layer (30). In the method, since xenon and krypton have heavy atoms and cannot be easily accelerated by an electromagnetic field, bombardment on interfaces of the reference layer (50) and the free layer (30) can be effectively reduced during physical vapor deposition, thereby allowing diffusion of interface materials to be better controlled, improving the spin polarization and the overall crystal orientation of the reference layer (50) and the free layer (30), and lowering the writing voltage of the device while reducing the RA thereof so as to improve the erase and write performance of the device.
