摘要

对不同接地栅极屏蔽结构的LDMOS器件进行了仿真和测试，旨在同时解决热载流子抗扰性和鲁棒性问题。优化的接地栅极屏蔽结构配置可以降低栅极-漏极重叠处的局部电场强度，从而获得更好的热载流子抗扰度;通过仿真和实测数据分析了热载波抗扰性和鲁棒性的设计权衡。

Design Tradeoff of Hot Carrier Immunity and Robustness in LDMOS with Grounded Gate Shield

LDMOS devices with grounded gate shield structures variations were simulated and tested, aiming to address hot carrier immunity and robustness concurrently. Optimal configuration of grounded gate shield structure was found to reduce local electrical field strength at gate-to-drain overlap for better hot carrier immunity, and to achieve uniform E-field distribution on drain side for robustness as well. Design trade off of hot carrier immunity (HCI) and robustness is analyzed by simulation and silicon data.
