为解决面向扫描电子显微镜 ( SEM) 的原位原子力显微镜 ( AFM) 工作时 SEM 的聚焦电子束引起原位 AFM 自感应压阻式微悬臂梁 ( PRC) 力传感器读数持续漂移的难题,首先建立原位 AFM 自感应 PRC 力传感器的 p 沟道结型场效应晶体管 ( JFET) 读数漂移模型,分析SEM 聚焦电子束对自感应 PRC 产生干扰的原因; |
In order to solve the problem of continuous reading drift of in-situ atomic force microscope(AFM) self-sensing piezoresistive cantilever (PRC) force sensor caused by focused electron beam of the scanning electron microscope (SEM) during the operation of in-situ AFM for the SEM, a p-channel junction field-effect transistor (JFET) of in-situ AFM self-sensing PRC force sensor reading drift was modeledand the reason of the SEM focused electron beam causing interference for self-sensing PRC was analyzed. |

即先对自感应 PRC 的栅极进行导电连接,再通过控制施加在自感应 PRC 栅极上的补偿电压消除 SEM 聚焦电子束对自感应 PRC 的干扰。 |
The interference of the SEM focused electron beam on the self-sensing PRCwas eliminated by adding an extra conductive connection to the gate of the self-sensing PRC and adjustingthe compensation voltage that applied to the gate of the self-sensing PRC. |

实验结果表明,当补偿电压从未施加上升至 40 V 时,原位 AFM 自感应 PRC 力传感器读数的漂移率从约 13 nm /min下降到 1 nm /min 左右,同时对自感应 PRC 及其信号调理电路均无损伤。 |
The experimental results show that the drift rate of the in-situ AFM self-sensing PRC force sensor is reduced from about 13 nm/min toabout 1 nm/min without any damage to the self-sensing PRC and its signal conditioning circuit when thecompensation voltage increases from unapplied to 40 V. |

该方法能有效消除 SEM聚焦电子束对原位 AFM 自感应 PRC 力传感器的影响。 |
