At high frequencies (typically 1 MHz), minority carriers cannot follow the rapid AC signal. Consequently, when the device enters inversion, the capacitance bottoms out at a minimum value determined by the maximum depletion width. when the device enters inversion

Modern high-k metal gate (HKMG) processing introduces significant interface and bulk oxide trapping phenomena. Engineers use the exact frequency-dependent conductance and capacitance-voltage (C-V) profiling methods pioneered by Nicollian and Brews to characterize and minimize these defects. when the device enters inversion
