Abstract
In this work, we have prepared metal-insulator-metal capacitors for dynamic random access memory capacitor application using atomic layer deposition of TiO2 high-κ dielectric and RuO2 bottom electrode. We compare TiO2 layers grown using TiCl4 precursor or Ti-tetra-isopropoxide precursor, and Al-doped TiO2 layers grown using Ti-tetra-isopropoxide precursor. The capacitors were analyzed in the terms of capacitance - voltage and current - voltage measurements and transmission electron microscopy imaging.
