Abstract :
In this paper we describe and demonstrate the use of gate-to-drain capacitance (Cgd) measurements at cryogenic temperature as a tool to characterize hot-carrier-induced charge centers. Also a new method based on gate-to-substrate capacitance (Cgb), validated by means of two-dimensional numerical simulation, is proposed to extract the spatial distribution of oxide interface charges with reasonable accuracy
