    摘要： Provided are inverse phase allotrope rare earth (IPARE) magnets, methods of forming thereof, and applications of IPARE magnets. Unlike conventional samarium-cobalt magnets, IPARE magnets maintain their hexagonal lattice structures over a range of equiatomic compositions, such as when concentrations of different elements are within 10 atomic % of each other. An IPARE magnet may comprise cobalt, iron, copper, nickel, and samarium and a concentration of cobalt may be between 17-27 atomic %. An IPARE magnet may be substantially free from zirconium and/or titanium. An IPARE magnet may be formed by quenching a molten mixture of its components. The quenching may be performed in a magnetic field. After quenching, the IPARE magnet may be machined. Furthermore, IPARE magnets may be used as a structural element, e.g. in an electric motor.

    摘要： In a “window-junction” formation process for Josephson junction fabrication, a spacer dielectric is formed over the first superconducting electrode layer, then an opening (the “window” is formed to expose the part of the electrode layer to be used for the junction. In an atomic layer deposition (ALD) chamber (or multi-chamber sealed system) equipped with direct or remote plasma capability, the exposed part of the electrode is sputter-etched with Ar, H2, or a combination to remove native oxides, etch residues, and other contaminants. Optionally, an O2 or O3 pre-clean may precede the sputter etch. When the electrode is clean, the tunnel barrier layer is deposited by ALD in-situ without further oxidant exposure.

    摘要： Provided are methods for processing semiconductor substrates or, more specifically, etching silicon containing antireflective coatings (SiARCs) from the substrates while preserving silicon oxides layers disposed on the same substrates. An etching solution including sulfuric acid and hydrofluoric acid may be used for these purposes. In some embodiments, the weight ratio of sulfuric acid to hydrofluoric acid in the etching solution is between about 15:1 and 100:1 (e.g., about 60:1). The temperature of the etching solution may be between about 30° C. and 50° C. (e.g., about 40° C., during etching). It has been found that such processing conditions provide a SiARC etching rate of at least about 50 nanometers per minute and selectivity of SiARC over silicon oxide of greater than about 10:1 or even greater than about 50:1. The same etching solution may be also used to remove photoresist, organic dielectric, and titanium nitride.

    摘要： Selector devices that can be suitable for memory device applications can have low leakage currents at low voltages to reduce sneak current paths for non selected devices, and high leakage currents at high voltages to minimize voltage drops during device switching. In some embodiments, the selector device can include a first electrode, a tri-layer dielectric layer, and a second electrode. The tri-layer dielectric layer can include a high leakage dielectric layer sandwiched between two lower leakage dielectric layers. The low leakage layers can function to restrict the current flow across the selector device at low voltages. The high leakage dielectric layer can function to enhance the current flow across the selector device at high voltages.

    摘要： Provided are light emitting diodes (LEDs) and methods of fabricating such LEDs. An LED may include a transparent conductive oxide (TCO) layer having a varying refractive index. For example, the refractive index may be higher at the interface of the TCO layer with an epitaxial stack than on the side of the TCO layer. The refractive index variability allows reducing light intensity losses in the LED. The refractive index variability may be achieved by feeding a substrate through a deposition chamber having a variable concentration of at least one process gas, such as oxygen. Specifically, the concentration of the process gas may be higher at one slit opening than at another slit opening. As the substrate moves through the deposition chamber, the TCO layer is continuously deposited. Due to the concentration variability, the resulting TCO layer may have a variable composition throughout the thickness of the TCO layer.
