[SMM] Scanning Microwave Microscopy Method

Scanning Microwave Microscopy

SMM scans the measurement sample using a conductive probe to observe its surface topography. Simultaneously, microwaves are irradiated from the probe to the sample, and by measuring the reflected response, it is possible to obtain signals correlated with carrier concentration, particularly in the case of semiconductors. The intensity of the SMM signal is linearly correlated with carrier concentration, which is a characteristic feature that provides high quantitativeness. - For Si devices, sensitivity is present for carrier concentrations around 10^15 to 10^20 cm^-3. - Since signals correlated linearly with carrier concentration can be obtained, quantitative evaluation (semi-quantitative) is possible under certain assumptions. - AFM images can also be acquired. - Various semiconductors such as Si, SiC, GaN, InP, and GaAs can be measured.
