    Abstract: This disclosure provides a method of fabricating a semiconductor stack and associated device, such as a capacitor or DRAM cell. In such a device, a high-K zirconia-based layer may be used as the primary dielectric together with a relatively inexpensive metal electrode based on titanium nitride. To prevent corruption of the electrode during device formation, a thin barrier layer can be used seal the electrode prior to the use of a high temperature process and a (high-concentration or dosage) ozone reagent (i.e., to create a high-K zirconia-based layer). In some embodiments, the barrier layer can also be zirconia-based, for example, a thin layer of doped or un-doped amorphous zirconia. Fabrication of a device in this manner facilitates formation of a device with dielectric constant of greater than 40 based on zirconia and titanium nitride, and generally helps produce less costly, increasingly dense DRAM cells and other semiconductor structures.

    Abstract: Methods for forming an electronic device having a fluorine-stabilized semiconductor substrate surface are disclosed. In an exemplary embodiment, a layer of a high-κ dielectric material is formed together with a layer containing fluorine on a semiconductor substrate. Subsequent annealing causes the fluorine to migrate to the surface of the semiconductor (for example, silicon, germanium, or silicon-germanium). A thin interlayer of a semiconductor oxide may also be present at the semiconductor surface. The fluorine-containing layer can comprise F-containing WSix formed by ALD from WF6 and SiH4 precursor gases. A precise amount of F can be provided, sufficient to bind to substantially all of the dangling semiconductor atoms at the surface of the semiconductor substrate and sufficient to displace substantially all of the hydrogen atoms present at the surface of the semiconductor substrate.

    Abstract: Molybdenum oxide can be used to form switching elements in a resistive memory device. The atomic ratio of oxygen to molybdenum can be between 2 and 3. The molybdenum oxide exists in various Magneli phases, such as Mo13O33, Mo4O11, Mo17O47, Mo8O23, or Mo9O26. An electric field can be established across the switching layers, for example, by applying a set or reset voltage. The electric field can cause movement of the oxygen charges, e.g., O2− ions, changing the composition profile of the switching layers, forming bistable states, including a high resistance state with MoO3 and a low resistance state with MoOx (x

    Abstract: A method for reducing the leakage current in DRAM Metal-Insulator-Metal capacitors includes forming a capacitor stack including an oxygen donor layer inserted between the dielectric layer and at least one of the two electrode layers. In some embodiments, the dielectric layer may be doped with an oxygen donor dopant. The oxygen donor materials provide oxygen to the dielectric layer and reduce the concentration of oxygen vacancies, thus reducing the leakage current.
