二次电子(SE)成像的掺杂对比主要由扫描电子显微镜(SEM)分析的固体样品表面的局部电子带结构决定。为了研究非均匀掺杂半导体的掺杂对比机制,我们采用基于有限元载流子和电位建模和SE发射和对比度检测蒙特卡罗模拟相结合的数值方法建立了定量模型。该组合模型能够区分试样内部场(表面带弯曲)、微观外场(贴片场)和SEM中应用的任何宏观外场的影响。
Dopant contrast from secondary electron (SE) imaging is essentially determined by the local electronic band structure at the surface of the solid specimen being analysed in the scanning electron microscope (SEM). To study dopant contrast mechanisms on inhomogeneously doped semiconductors, we have developed a quantitative model by using a numerical method based on a combination of finite-element carrier and potential modelling and Monte Carlo simulation of SE emission and contrast detection. This combined model enables distinction between the effects of specimen internal fields (surface band-bending), microscopic external fields (patch fields) and any macroscopic external fields applied in the SEM.
