Abstract

In this study, a novel dual- k spacer ferroelectric field-effect transistor (FeFET) structure is proposed. By adopting the dual- k spacer for the first time in FeFET, the target memory window (MW) of 0.5 V is achievable at a write voltage of 5 V. The write voltage shows a 2.0-V reduction from 7 V for the low- k spacer FeFET (L-FeFET) and a 1.0-V reduction from 6 V for the high- k spacer FeFET (H-FeFET). The write power of the proposed FeFET was 25.9% lower than that of the low- k FeFET and H-FeFET. These improvements significantly expand the Pareto front and mitigate the effects of trapped charge. The dual- k spacer FeFET structure is a promising candidate for low-voltage and low-power operations.

利用双 k 隔板扩展铁电场效应晶体管的帕雷托前沿

本研究提出了一种新型双 k 间距铁电场效应晶体管 (FeFET) 结构。通过首次在铁电场效应晶体管中采用双 k 间距，可在 5 V 写入电压下实现 0.5 V 的目标存储窗口 (MW)。低 k 值间隔 FeFET（L-FeFET）的写入电压比 7 V 降低了 2.0 V，而高 k 值间隔 FeFET（H-FeFET）的写入电压比 6 V 降低了 1.0 V。拟议的 FeFET 的写入功率比低 k FeFET 和 H-FeFET 低 25.9%。这些改进大大扩展了帕累托前沿，并减轻了陷波电荷的影响。双 k 间距 FeFET 结构是低电压和低功耗操作的理想候选器件。
