  • Patent number: 8576615
    Abstract: A magnetic random access memory (“MRAM”) cell includes: (1) a first magnetic layer having a first magnetization direction and a magnetic anisotropy axis; (2) a second magnetic layer having a second magnetization direction; and (3) a spacer layer disposed between the first magnetic layer and the second magnetic layer. The MRAM cell also includes a field line magnetically coupled to the MRAM cell and configured to induce a write magnetic field along a magnetic field axis, and the magnetic anisotropy axis is tilted relative to the magnetic field axis. During a write operation, the first magnetization direction is switchable between m directions to store data corresponding to one of m logic states, with m>2, at least one of the m directions is aligned relative to the magnetic anisotropy axis, and at least another one of the m directions is aligned relative to the magnetic field axis.

  • Patent number: 7691712
    Abstract: Semiconductor device structures and fabrication methods for field effect transistors in which a gate electrode is provided with an air gap or void disposed adjacent to a sidewall of the gate electrode. The void may be bounded by a dielectric spacer proximate to the sidewall of the gate electrode and a dielectric layer having a spaced relationship with the dielectric spacer. The methods of the invention involve the use of a temporary spacer consisting of a sacrificial material supplied adjacent to the sidewall of the gate electrode, which is removed after the dielectric layer is formed.
