Abstract

The reliability of an Al-doped HfO $_{2}$ dielectric used in a high density 2.5D MIMCAP is investigated by constant voltage stress (CVS) and voltage ramp stress (VRS) measurements. The good agreement of the results from the two techniques allows to propose a model for lifetime prediction based on the breakdown characteristics. The extracted activation energy shows a voltage dependence associated with a change in the degradation characteristics of the high- $κ$ material at high fields.

基于电压斜坡应力的 2.5d mimcaps 高级掺铝 hfo2 介电寿命预测模型

通过恒压应力（CVS）和电压斜坡应力（VRS）测量，研究了用于高密度 2.5D MIMCAP 的掺铝 HfO2 介电材料的可靠性。两种技术得出的结果非常吻合，因此可以根据击穿特性提出寿命预测模型。提取的活化能显示出电压依赖性，这与高κ材料在高电场下的降解特性变化有关。
