ABSTRACT:
The true electrical channel length of a surface FET is determined by obtaining individual electron-beam-induced-current signal traces of source and drain junctions, thus eliminating the coupling effect of the two junctions. A reliable mask is formed as a function of the measured peak-to-peak distance subtracted by the depletion width.
