Abstract

The precise characterization of the doping profile is crucial for optimizing the performance and structural integrity of semiconductor devices. As the size of semiconductor devices continues to diminish, the need of precise characterization of doping profiles has become increasingly urgent. Atomic Force Microscopy (AFM) has become a promising technique for doping profile characterization within the semiconductor field, owing to its high spatial resolution, multidimensional feature analysis, and flexibility in various working environments. Based on AFM technology, various techniques have been developed for doping characterization, such as scanning capacitance microscope (SCM), scanning spreading resistance microscope (SSRM) and scanning microwave impedance microscope (sMIM). In this work, we systematically review the application of these three techniques for doping characterization and summarize their strengths and limitations. Furthermore, we also evaluate their capability in characterizing the doping profiles of miniature devices with three-dimensional (3D) architectures. This work offers feasible approaches for advanced semiconductor device manufacturing.
