  • Patent number: 9166161
    Abstract: A phase change memory cell and a method for fabricating the phase change memory cell. The phase change memory cell includes a bottom electrode and a first non-conductive layer. The first non-conductive layer defines a first well, a first electrically conductive liner lines the first well, and the first well is filled with a phase change material in the phase change memory cell. A second non-conductive layer is deposited above the first non-conductive layer. A second well is defined by the second non-conductive layer and positioned directly above the first well. A second electrically conductive liner lines at least one wall of the second well such that the second electrically conductive liner is not in physical contact with the first electrically conductive liner. Furthermore, the phase change material is deposited in the second well.

  • Patent number: 9159920
    Abstract: An example embodiment disclosed is a process for fabricating a phase change memory cell. The method includes forming a bottom electrode, creating a pore in an insulating layer above the bottom electrode, depositing piezoelectric material in the pore, depositing phase change material in the pore proximate the piezoelectric material, and forming a top electrode over the phase change material. Depositing the piezoelectric material in the pore may include conforming the piezoelectric material to at least one wall defining the pore such that the piezoelectric material is deposited between the phase change material and the wall. The conformal deposition may be achieved by chemical vapor deposition (CVD) or by atomic layer deposition (ALD).

  • Publication number: 20150269984
    Abstract: A nonvolatile memory storage device includes a ferroelectric (FE) material coupled with a piezoresistive (PR) material through an inherent piezoelectric response of the FE material, wherein an electrical resistance of the PR material is dependent on a compressive stress applied thereto, the compressive stress caused by a remanent strain of the FE material resulting from a polarization of the FE material, such that a polarized state of the FE material results in a first resistance value of the PR material, and a depolarized state of the FE material results in a second resistance value of the PR material.

  • Patent number: 9105583
    Abstract: A material can be locally etched with arbitrary changes in the direction of the etch. A ferromagnetic-material-including catalytic particle is employed to etch the material. A wet etch chemical or a plasma condition can be employed in conjunction with the ferromagnetic-material-including catalytic particle to etch a material through a catalytic reaction between the catalytic particle and the material. During a catalytic etch process, a magnetic field is applied to the ferromagnetic-material-including catalytic particle to direct the movement of the particle to any direction, which is chosen so as to form a contiguous cavity having at least two cavity portions having different directions. The direction of the magnetic field can be controlled so as to form the contiguous cavity in a preplanned pattern, and each segment of the contiguous cavity can extend along an arbitrary direction.
