  4. 4. Silicon Oxynitride Thin Films Grown by Reactive HiPIMS

    Author : Tuomas Hänninen; Hans Högberg; Susann Schmidt; Lars Hultman; Jón Tómas Guðmundsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Amorphous silicon oxynitride (SiOxNy) thin films were grown by reactive high power impulse magnetron sputtering from a pure silicon target in Ar/N2O plasmas. The elemental composition of the films was shown to depend on the target surface conditions during the film deposition, as well as on the reactive gas flow rate. READ MORE
