Methods of forming integrated circuit devices having a capacitor with a hydrogen barrier spacer on a sidewall thereof and integrated circuit devices formed thereby

摘要

An integrated circuit device is formed by providing a substrate and forming a capacitor on the substrate. The capacitor includes a lower electrode disposed on the substrate, a dielectric layer on the lower electrode, and an upper electrode on the dielectric. A hydrogen barrier insulation layer is formed on the upper electrode and a hydrogen barrier spacer is formed on a sidewall of the capacitor.
