  • MATERIAL DEPOSITION METHOD AND MICROSYSTEM THEREWITH OBTAINED
    Publication number: 20240088202
    Abstract: A material deposition method comprising: providing a substrate; forming a film of HfO2 by chemical solution deposition, CSD, on the substrate; depositing a solution of PbTiO3 on the film of HfO2; depositing a layer of Pb(Zrx,Ti1-x)O3 on the seed layer, where O?x?1; and forming interdigitated electrodes on the Pb(Zrx,Ti1-x)O 3 layer. Also a ferroelectric microsystem obtained by this deposition method. Experiments show an improved fatigue resistance for such a microsystem.
