Abstract
A method for manufacturing an integrated circuit having a magnetic tunnel junction device is disclosed. The method includes depositing a bottom pinning structure above the bottom conductive structure. A first ferromagnetic structure is deposited above the bottom pinning structure in a chamber. A tunnel barrier structure is deposited above the first ferromagnetic layer structure in the chamber, and a second ferromagnetic structure is deposited above the tunnel barrier structure of the magnetic tunnel junction device in another chamber.
