Summary:
This work presents an overview and an update on resistance mapping in Scanning Electron Microscopy (SEM) using Electron Beam Absorbed Current (EBAC) signals acquired with nanoprobing systems. Recent advances include integration into the nanoprobing platform of dedicated in situ electronics to minimize noise and increase speed, as well as a transition to voltage sensitive amplification to improve resistance sensitivity beyond the 10 Ohms range and to allow for mapping of resistors as low as 100 Ohms.
