Atomic Force Microscope
The wafer-level atomic force microscope uses a micro-cantilever probe structure to characterize the three-dimensional appearance of solid materials such as conductors, semiconductors, and insulators, and can test large wafer-level samples.
The electric sample positioning stage combined with optical imaging can achieve a positioning accuracy of 1 µm in a 300X300 mm area. The probe approach and scanning parameter adjustment are fully automated, and the imaging resolution can reach 20 picometers.
