Abstract
(Sr$\sub$0.85/Ca$\sub$0.15/)TiO$_3$thin films were deposited on Pt-coated TiO$_2$/SiO$_2$/Si wafer by the rf sputtering method. Experiments were conducted to investigate the electrical properties of SCT thin films with various top electrode. C-F and C-V measurements show that SCT thin films annnealed at 600$^{\circ}C$ have a larger capacitance than SCT thin films deposited at 400$^{\circ}C$ , and there is nearly no difference between top electrodes. I-V measurement show that Pt top electrode have a good leakage current density of < 10nA/$\textrm{cm}^2$,. making them suitable for DRAM application.
