Abstract: Transistors and integrated circuitry including a 2D channel material layer within a stack of material layers further including one or more insulator (e.g., dielectric) materials above and/or below the 2D channel material layer. These supporting insulator layers may be non-sacrificial while other material layers within a starting material stack may be sacrificial, replaced, for example, with gate insulator and/or gate material. In some exemplary embodiments, the 2D channel material is a metal chalcogenide and the supporting insulator layer is advantageously a dielectric material composition having a low dielectric constant.

Abstract: Material layer stack structures to provide a magnetic tunnel junction (MTJ) having improved perpendicular magnetic anisotropy (PMA) characteristics. In an embodiment, a free magnetic layer of the material layer stack is disposed between a tunnel barrier layer and a cap layer of magnesium oxide (Mg). The free magnetic layer includes a Cobalt-Iron-Boron (CoFeB) body substantially comprised of a combination of Cobalt atoms, Iron atoms and Boron atoms. A first Boron mass fraction of the CoFeB body is equal to or more than 25% (e.g., equal to or more than 27%) in a first region which adjoins an interface of the free magnetic layer with the tunnel barrier layer. In another embodiment, the first Boron mass fraction is more than a second Boron mass fraction in a second region of the CoFeB body which adjoins an interface of the free magnetic layer with the cap layer.

Abstract: Techniques are disclosed for carrying out ferromagnetic resonance (FMR) testing on whole wafers populated with one or more buried magnetic layers. The techniques can be used to verify or troubleshoot processes for forming the buried magnetic layers, without requiring the wafer to be broken. The techniques can also be used to distinguish one magnetic layer from others in the same stack, based on a unique frequency response of that layer. One example methodology includes moving a wafer proximate to a waveguide (within 500 microns, but without shorting), energizing a DC magnetic field near the target measurement point, applying an RF input signal through the waveguide, collecting resonance spectra of the frequency response of the waveguide, and decomposing the resonance spectra into magnetic properties of the target layer. One or both of the DC magnetic field and RF input signal can be swept to generate a robust set of resonance spectra.
