    摘要: A multi-layer PrxCa1-xMnO3 (PCMO) thin film capacitor and associated deposition method are provided for forming a bipolar switching thin film. The method comprises: forming a bottom electrode; depositing a nanocrystalline PCMO layer; depositing a polycrystalline PCMO layer; forming a multi-layer PCMO film with bipolar switching properties; and, forming top electrode overlying the PCMO film. If the polycrystalline layers are deposited overlying the nanocrystalline layers, a high resistance can be written with narrow pulse width, negative voltage pulses. The PCMO film can be reset to a low resistance using a narrow pulse width, positive amplitude pulse. Likewise, if the nanocrystalline layers are deposited overlying the polycrystalline layers, a high resistance can be written with narrow pulse width, positive voltage pulses, and reset to a low resistance using a narrow pulse width, negative amplitude pulse.

The method comprises: forming a bottom electrode; forming an electrical pulse various resistance (EPVR) first layer having a polycrystalline structure over the bottom electrode; forming an EPVR second layer adjacent the first layer, with a nano-crystalline or amorphous structure; and, forming a top electrode overlying the first and second EPVR layers.

    摘要: A fabrication process provides for achieving high adhesion of CVD copper thin films on metal nitride substrates, and in particular, on substrates having an outermost TaN layer. The method comprises introducing a certain amount of water vapor to the initial copper thin film deposition stage and reducing the amount of fluorine in the interface of the copper and metal nitride substrate. These two process steps result in a copper thin film having improved adhesion to metal nitride substrates, including TaN substrates.

    摘要: A method is provided for forming a rare earth element-doped silicon oxide (SiO2) precursor with nanocrystalline (nc) Si particles. In one aspect the method comprises: mixing Si particles into a first organic solvent, forming a first solution with a first boiling point; filtering the first solution to remove large Si particles; mixing a second organic solvent having a second boiling point, higher than the first boiling point, to the filtered first solution; and, fractionally distilling, forming a second solution of nc Si particles. The Si particles are formed by immersing a Si wafer into a third solution including hydrofluoric (HF) acid and alcohol, applying an electric bias, and forming a porous Si layer overlying the Si wafer. Then, the Si particles are mixed into the organic solvent by depositing the Si wafer into the first organic solvent, and ultrasonically removing the porous Si layer from the Si wafer.
