Abstract

In this work, for the first time at our knowledge, the improvement of chalcogenide-based CBRAM performance and reliability by Sb doping of the GeS2 electrolyte is presented. An original analysis, based on in-depth physico-chemical characterization, device electrical measurements, empirical model and first principle calculations, is shown. We argue that optimized ~10% Sb doping in the GeS2 electrolyte allows to achieve SET speed of 30ns at 2.2V (i.e. 0.66pJ SET programming power), while assuring 10 years data retention at 125°C, >105 cycling and high robustness to Sn-Pb soldering profile. Finally, the improved thermal stability of the filament in the GeS2-Sb matrix is clearly elucidated by means of molecular dynamics calculations.
sb掺杂GeS2在导电桥式RAM中的性能和可靠性提升
在这项工作中,据我们所知,首次提出了通过Sb掺杂GeS2电解质来改善硫族化合物基CBRAM性能和可靠性的方法。基于深入的物理化学表征、器件电测量、经验模型和第一性原理计算的原始分析显示。我们认为,在GeS2电解液中掺杂~10%的Sb可以在2.2V(即0.66pJ SET编程功率)下实现30ns的SET速度,同时保证在125°C下10年的数据保留,>105次循环和对Sn-Pb焊接曲线的高鲁棒性。最后,通过分子动力学计算清楚地阐明了GeS2-Sb基体中长丝的热稳定性的提高。
