摘要

本文介绍了一种名为 "沙漏晶体管 "的新型 MOSFET 布局，旨在改善其在总电离剂量（TID）效应下的电气性能。这种新型耐辐射器件的基础是增加寄生沟道电阻、利用纵向转角效应（LCE）改变电场以及降低中央栅极区域内的沟道电阻。该辐射防护 MOS 结构设计是在 130 纳米 CMOS 体工艺中实现的，并通过三维物理模型对其性能进行了仿真分析。将所提出的沙漏晶体管与矩形、菱形、狗骨和 H 门器件进行了比较，结果显示辐射后 Ioff 电流分别降低了 8.77 倍、4.6 倍、1.85 倍和 13.7 倍；辐射前归一化饱和电流分别增加了 2.29 倍、1.04 倍、1.58 倍和 1.52 倍，而栅极面积分别增加了 4.84 倍、1 倍、2.47 倍和 2.03 倍。

Hourglass transistor: An alternative and improved MOS structure robust to total ionization dose radiation

This paper presents a novel MOSFET layout named the “hourglass transistor”, aimed to improve its electrical behavior under Total Ionizing Dose (TID) effects. The new radiation-tolerant device is based on augmenting parasitic channel resistance, alteration of the electric field by the longitudinal corner effect (LCE), and reducing channel resistance within the central gate region. The radiation-robust MOS structure design was implemented in a 130 nm CMOS bulk process and its performance was analyzed through simulations using 3D physical models. The proposed hourglass transistor was compared with rectangular, diamond, dog bone and H-gate devices, showing a reduction in the post-radiation $I_{o f f}$ current of 8.77, 4.6, 1.85 and 13.7 times, respectively; and a pre-radiation normalized saturation current of 2.29, 1.04, 1.58 and 1.52 times greater with an increase of 4.84, 1, 2.47 and 2.03 times the gate area, respectively.
