Method for fabricating synthetic antiferromagnetic (SAF) device |
摘要 |
A method for fabricating a synthetic antiferromagnetic device, includes depositing a reference layer on a first tantalum layer and including depositing a first cobalt iron boron layer, depositing a second cobalt iron boron layer on the first cobalt iron boron layer, depositing a second Ta layer on the second cobalt iron boron layer, depositing a magnesium oxide spacer layer on the reference layer and depositing a cap layer on the magnesium oxide spacer layer. |

1. A method for fabricating a synthetic antiferromagnetic (SAF) device, the method comprising:
depositing a reference layer on a first tantalum layer and including:
depositing a first cobalt iron boron (CoFeB) layer;depositing a second CoFeB layer on the first CoFeB layer;depositing a second Ta layer on the second CoFeB layer; depositing a magnesium oxide (MgO) spacer layer on the reference layer; and depositing a cap layer on the MgO spacer layer. |
