摘要： A Cu(hfac) precursor with a substituted ethylene ligand has been provided. The substituted ethylene ligand includes bonds to molecules selected from the group consisting of C.sub.1 to C.sub.8 alkyl, C.sub.1 to C.sub.8 haloalkyl, H, and C.sub.1 to C.sub.8 alkoxyl. One variation, the 2-methyl-1-butene ligand precursor has proved to be stable at room temperature, and extremely volatile at higher temperatures. Copper deposited with this precursor has low resistivity and high adhesive characteristics. Because of the volatility, the deposition rate of copper deposited with this precursor is very high. A synthesis method has been provided which produces a high yield of the above-described precursor.

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.

摘要： A method for using a Cu(hfac) precursor with a substituted phenylethylene ligand to form an adhesive seed layer on an IC surface has been provided. The substituted phenylethylene ligand includes bonds to molecules selected from the group consisting of C1 to C6 alkyl, C1 to C6 haloalkyl, phenyl, H and C1 to C6 alkoxyl. One variation, the &agr;-methylstyrene ligand precursor has proved to be especially adhesive. Copper deposited with this precursor has low resistivity and high adhesive characteristics. The seed layer provides a foundation for subsequent Cu layers deposited through either CVD, PVD, or electroplating. The adhesive seed layer permits the subsequent Cu layer to be deposited through an economical high deposition rate process.
