Abstract

The electrical properties of Ru/SrTiOx/Ru capacitors have been investigated. Equivalent Oxide Thickness (EOT) of 0.38 nm at 0 V and current density of 10-7 A cm-2 at ±1 V and 25 °C meet the sub-20 nm DRAM requirements. Relaxation measurements were performed, indicating acceptable charge loss. Modeling of charge trapping at defect sites based on multi-phonon trap-assisted-tunneling quantitatively well describes leakage and capacitance behavior.
