Non-destructive thickness measurement of Si wafers via optical third-harmonic generation with femtosecond laser pulses
Si wafers are vital substrate materials in semiconductor manufacturing and require precise non-destructive thickness measurements. However, the conventional electrical and optical measurement techniques are limited by depth selectivity and system complexity. Here, we propose a simple, high-precision...
