Abstract

This paper reports detailed analysis on switching dynamics and device variability over a wide range of temperatures for deeply scaled (40nm gate length) tri-gate ferroelectric FETs with 10nm HZO fabricated using gate first process on SOI wafers. Our experimental results manifest, 99% ferroelectric switching at room temperature and at 233K. A memory window over 5V and strong gate length dependence of memory window is observed. Highly linear and symmetric multilevel switching characteristics makes our ferroelectric FETs suitable for neuromorphic applications, as demonstrated with neural network online training simulations.
