    摘要: A semiconductor device and fabrication method thereof. The semiconductor device comprises a substrate, an electroactive organic layer with conformal step coverage and uniform thickness, and a metal layer. The substrate is a conductive substrate or a nonconductive substrate with a conductive layer formed thereon. The electroactive organic layer and the metal layer are formed sequentially on the conductive substrate or the conductive layer, wherein the electroactive organic layer comprises metal atoms and serves as a seed layer, resulting in the metal layer formed in-situ.

    摘要: A process for improving the adhesion between an underlying copper structure, and overlying materials and structures, has been developed. The process features formation of a tantalum nitride layer on a copper structure, wherein the copper structure is located in a damascene type opening. To obtain the maximum adhesion benefit the tantalum nitride layer is formed via an atomic deposition layer procedure, performed at specific deposition conditions. The adhesion between the underlying copper structure and overlying materials such as a silicon nitride etch stop layer, as well the adhesion between the lower level copper structure and overlying upper level metal interconnect structures, is improved as a result of the presence of the atomic layer deposited tantalum nitride layer.

    摘要: An ALD method is described for depositing a composite layer comprised of three to five elements including one or two metals, Si, B and N. A metal containing gas is injected into a process chamber and purged followed by a N source gas and a purge and/or a Si or B source gas and a purge to complete a cycle and form a monolayer. A predetermined number of monolayers each having two or three elements is deposited to provide a composite film with good step coverage and a well controlled composition. The resulting layer is especially useful as a diffusion barrier layer for copper. Alternatively, a three component layer comprised of Hf, Zr, and O may be deposited and serves as a gate dielectric layer in a MOSFET device. The invention is also a thin film comprised of a plurality of monolayers each having two or three elements.
