Abstract:
Embodiments herein provide methods of forming a magnetic tunnel junction structure. The method includes forming a film stack that includes: a buffer layer; a seed layer disposed over the buffer layer; a first pinning layer disposed over the seed layer; a synthetic ferrimagnet (SyF) coupling layer disposed over the first pinning layer; a second pinning layer disposed over the SyF coupling layer; a structure blocking layer disposed over the second pinning layer; a magnetic reference layer disposed over the structure blocking layer; a tunnel barrier layer disposed over the magnetic reference layer; a magnetic storage layer disposed over the tunnel barrier layer; a capping layer disposed over the magnetic storage layer; and a hard mask disposed over the capping layer, wherein at least one of the capping layer, the buffer layer, and the SyF coupling layer is not fabricated from Ru; and forming a magnetic tunnel junction structure.

Claim (Index 15):
A method of forming a magnetic tunnel junction structure, comprising:\n forming a film stack comprising: a buffer layer, wherein the buffer layer comprises a CoFeB containing layer; a seed layer disposed over the buffer layer; a first pinning layer disposed over the seed layer; a synthetic ferrimagnet (SyF) coupling layer disposed over the first pinning layer, wherein the SyF coupling layer comprises an Ir containing layer; a second pinning layer disposed over the SyF coupling layer; a structure blocking layer disposed over the second pinning layer; a magnetic reference layer disposed over the structure blocking layer; a tunnel barrier layer disposed over the magnetic reference layer; a magnetic storage layer disposed over the tunnel barrier layer; a capping layer disposed over the magnetic storage layer, wherein the capping layer comprises one or more layers; and a hard mask disposed over the capping layer, wherein at least one of the capping layer, the buffer layer, and the SyF coupling layer is not fabricated from Ru, and wherein forming a stack comprises depositing a cobalt containing layer; and forming a magnetic tunnel junction structure.
