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 8):
The method of  claim 1 , wherein the capping layer comprises:\n (a) an Ir containing layer, a Ru containing layer, or a combination thereof as a top layer; and an oxygen containing layer, wherein the top layer is disposed directly above the oxygen containing layer; or (b) an Ir containing layer as a top layer; and one or more of a W containing layer, an oxygen containing layer, a second Ir containing layer disposed directly above the oxygen containing layer, a CoFeB containing layer, a Ta containing layer, and a Mo containing layer.
