  • Patent number: 7510639
    Abstract: Plating baths containing a mixture of leveling agents, where the mixture includes a first level agent having a first diffusion coefficient and a second leveling agent having a second diffusion coefficient, are provided. Such plating baths deposit a metal layer, particularly a copper layer, that is substantially planar across a range of electrolyte concentrations. Methods of depositing metal layers using such plating baths are also disclosed. These baths and methods are useful for providing a planar layer of copper on a substrate having small apertures, such as an electronic device.

  • Publication number: 20090020434
    Abstract: A substrate processing method makes it possible to fill interconnect recesses, such as trenches, with a defect-free interconnect material by carrying out electroplating directly on a surface of a ruthenium film as a barrier layer. The substrate processing method comprises: providing a substrate having interconnect recesses formed in a substrate surface and having a ruthenium film formed in the entire substrate surface including interior surfaces of the interconnect recesses; keeping the substrate surface in contact with a plating solution for a predetermined time to adsorb an additive in the plating solution onto the ruthenium film, and then carrying out electroplating to form a conductive film on a surface of the ruthenium film.

  • Patent number: 7297868
    Abstract: A photovoltaic cell exhibiting an overall conversion efficiency of at least 9.0% is prepared from a copper-indium-gallium-diselenide thin film. The thin film is prepared by simultaneously electroplating copper, indium, gallium, and selenium onto a substrate using a buffered electro-deposition bath. The electrodeposition is followed by adding indium to adjust the final stoichiometry of the thin film.
