Abstract

In this study, the electrical performance and evolution of point defects in chip-level Silicon-based MOSFET under transmission line pulse (TLP) stress were investigated. The experimental results show that the threshold voltage decreased by 9.8%, and the output saturation current increased by 5.9% after the stress. An intrinsic point defect with an energy level of

$0.25~\pm ~0.05$

eV in Si-based MOSFET chips was observed by using deep-level transient spectroscopy (DLTS), which shifted to

$0.37~\pm ~0.05$

eV after the stress. The increase of the trap energy level would reduce the holes at the Si/SiO2 interface, and herein the threshold voltage reduced. This work helps to further understand the evolution of point defects in Si-based MOSFET chips.

传输线脉冲应力下芯片级硅基 MOSFET 中点状缺陷的演变

本研究对传输线脉冲（TLP）应力下芯片级硅基 MOSFET 的电气性能和点缺陷的演变进行了研究。实验结果表明，应力作用后，阈值电压降低了 9.8%，输出饱和电流增加了 5.9%。利用深电平瞬态光谱（DLTS）观察到硅基 MOSFET 芯片中存在一个能级为 0.25~pm ~0.05$ eV 的本征点缺陷，在应力作用后，该能级转移到了 0.37~pm ~0.05$ eV。阱能级的增加会减少硅/二氧化硅界面上的空穴，从而降低阈值电压。这项工作有助于进一步了解硅基 MOSFET 芯片中点缺陷的演变。
