A first precursor comprising one rare earth element, a second precursor comprising barium, and a third precursor comprising copper are dissolved into acid to form a compound solution, the compound solution is dissolved into solvent to form a pre-precursor solution, and the solvent of the pre-precursor solution is evaporated to form a precursor solution with the increased viscosity. A sufficiently thick film can be formed without any cracking through only one-time coating.Type: ApplicationFiled: July 20, 2009Publication date: January 20, 2011Applicants: Seoul National University Industry Foundation, SUNAM CO., LTD.Inventors: Sang-Im YOO, Seung-Hyun Moon, Geo-Myung Shin

Patent number: 7786011Abstract: Compositions and methods for forming metal films on semiconductor substrates are disclosed. One of the disclosed methods comprises: heating the semiconductor substrate to obtain a heated semiconductor substrate; exposing the heated semiconductor substrate to a composition containing at least one metal precursor comprising at least one ligand, an excess amount of neutral labile ligands, a supercritical solvent, and optionally at least one source of B, C, N, Si, P, and mixtures thereof; exposing the composition to a reducing agent and/or thermal energy at or near the heated semiconductor substrate; disassociating the at least one ligand from the metal precursor; and forming the metal film while minimizing formation of metal oxides.Type: GrantFiled: January 25, 2008Date of Patent: August 31, 2010Assignee: Lam Research CorporationInventor: Mark Ian Wagner

Patent number: 7717987Abstract: The copper-indium-gallium (CuInGa) alloy is in particular to be used for the production of sputter targets, tubular cathodes and similar coating material sources. It has a phase corresponding to a Cu5Zn8 prototype phase in which the lattice sites of the zinc atoms (Zn) are occupied by gallium atoms (gallium-substituted Cu5Zn8 phase) and in which indium is simultaneously introduced into the elementary cell or phase, making up a proportion of up to 26 wt %.Type: GrantFiled: November 20, 2007Date of Patent: May 18, 2010Assignee: GfE Metalle und Materialien GmbHInventors: Karl-Uwe van Osten, Stefan Britting
