“The voltage contrast imaging of a semiconductor device with FE-SEM”
Contact plug surface in SRAM area was observed with FE-SEM. At low accelerating voltage, surface potential of each plug varies by lower structure and the resultant difference in SE emission provides high-contrast image to identify NMOS, PMOS and gate area.
