B. Ricco et al., EXTRACTION OF OXIDE THICKNESS FROM HARMONIC DISTORTION OF DISPLACEMENT CURRENTS IN MOS CAPACITORS, I.E.E.E. transactions on electron devices, 44(9), 1997, pp. 1552-1554
This brief presents a new experimental technique to determine the thic
kness of (thin) insulator films from the analysis of the. harmonic dis
torsion of the displacement current due to the nonlinearity of the C-V
characteristics of MOS capacitors. Such a method substantially improv
es the state of tile art, as it overcomes the noise problem affecting
a precious technique, particularly suitable for thin insulators since
it operates in the virtual absence of tunneling current and other comp
lex phenomena.
