Abstract :
This paper deals with the investigation of the LDMOSFET saturation mechanisms via 2D numerical simulations and experiments. A clear separation between the saturation of intrinsic MOS transistor and complex quasi-saturation mechanisms is made using the intrinsic drain concept. A modelling strategy for drain current based on the experimental extraction of the drift series resistance is presented. Very good model performances using a BSIM3v3 low voltage model combined with the proposed drift resistance extracted values are reported
