4. Silicon Oxynitride Thin Films Grown by Reactive HiPIMS
Sammanfattning : 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. LÄS MER
