摘要

FinFET分栅金属氮化氧化物硅(SG-MONOS)快闪存储器首次被制备并运行。由于鳍状结构,优异的亚阈值特性和小的阈值电压变异性得到了澄清。结果表明,采用增量阶跃脉冲规划可以很好地抑制源侧注入的翅片顶角效应。在250K程序/擦除周期后,在150°C下高度可靠的数据保留已被确认用于先进的汽车系统应用。

First demonstration of FinFET split-gate MONOS for high-speed and highly-reliable embedded flash in 16/14nm-node and beyond
FinFET split-gate metal-oxide nitride oxide silicon (SG-MONOS) Flash memories have been fabricated and operated for the first time. Excellent subthreshold characteristics and small threshold-voltage variability owing to a Fin-structure are clarified. It is demonstrated that Fin top-corner effects are well suppressed by incremental step pulse programming for source side injection. Highly reliable data retention at 150 °C after 250K program/erase cycles is confirmed for advanced automotive system applications.
