  • Patent number: 9590054
    Abstract: Embodiments of the present invention provide semiconductor structures and methods for making the same that include a boron nitride (BN) spacer on a gate stack, such as a gate stack of a planar FET or FinFET. The boron nitride spacer is fabricated using atomic layer deposition (ALD) and/or plasma enhanced atomic layer deposition (PEALD) techniques to produce a boron nitride spacer at relatively low temperatures that are conducive to devices made from materials such as silicon (Si), silicon germanium (SiGe), germanium (Ge), and/or III-V compounds. Furthermore, the boron nitride spacer may be fabricated to have various desirable properties, including a hexagonal textured structure.

  • Patent number: 9324564
    Abstract: Laser ablation can be used to form a trench within at least a blanket layer of a stressor layer that is atop a base substrate. A non-ablated portion of the stressor layer has an edge that defines the edge of the material layer region to be spalled. Laser ablation can also be used to form a trench within a blanket material stack including at least a plating seed layer. A stressor layer is formed on the non-ablated portions of the material stack and one portion of the stressor layer has an edge that defines the edge of the material layer region to be spalled. Laser ablation can be further used to form a trench that extends through a blanket stressor layer and into the base substrate itself. The trench has an edge that defines the edge of the material layer region to be spalled.

  • 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.

  • Patent number: 9059073
    Abstract: A method of removing a semiconductor device layer from a base substrate is provided that includes providing a crack propagation layer on an upper surface of a base substrate. A semiconductor device layer including at least one semiconductor device is formed on the crack propagation layer. Next, end portions of the crack propagation layer are etched to initiate a crack in the crack propagation layer. The etched crack propagation layer is then cleaved to provide a cleaved crack propagation layer portion to a surface of the semiconductor device layer and another cleaved crack propagation layer portion to the upper surface of the base substrate. The cleaved crack propagation layer portion is removed from the surface of the semiconductor device layer and the another cleaved crack propagation layer portion is removed from the upper surface of the base substrate.
