    摘要: A ferroelectric device includes a bottom electrode on which are formed ferrocapacitor elements and, over the ferroelectric elements, top electrodes. The bottom electrodes are connected to lower layers of the device via conductive plugs, and the plugs and bottom electrodes are spaced apart by barrier elements of Ir and/or IrO2. The barrier elements are narrower than the bottom electrode elements, and are formed by a separate etching process. This means that Ir fences are not formed during the etching of the bottom electrode. Also, little Ir and/or IrO2 diffuses through the bottom electrode to the ferroelectric elements, and therefore there is little risk of damage to the ferroelectric material.

    摘要翻译: 铁电体元件包括底电极,其上形成有铁电体元件,并且在铁电元件上形成顶电极。 底部电极通过导电插头连接到器件的下层,并且插头和底部电极被Ir和/或IrO 2的阻挡元件隔开。 阻挡元件比底部电极元件窄,并且通过单独的蚀刻工艺形成。 这意味着在底电极的蚀刻期间不形成Ir栅栏。 此外,很少的Ir和/或IrO 2 <2>通过底部电极扩散到铁电体元件,因此几乎不会损坏铁电体材料的风险。

    摘要: An Iridium barrier layer is between a contact plug and a bottom electrode of a capacitor. Etching is performed to pattern the bottom electrode and barrier layer using a fluorine-based recipe resulting in the formation of a first fence clinging to the sidewalls. Next the remaining barrier layer is etched using a CO-based recipe. A second fence is formed clinging to and structurally supported by the first fence. At the same time, the CO-based recipe etches away a substantial portion of the first fence to remove the structural support provided to the second fence. The second fence is therefore lifted-off from the sidewalls leaving the sidewalls substantially free of clinging fences. The etched barrier layer has a sidewall transition. The sidewalls have a relatively low taper angle above the sidewall transition and a relatively steep taper angle below the sidewall transition.
