Spatial and spectral oxide trap distributions in power MOSFETs
Charge trapping features of a power MOSFET oxide are investigated by irradiation and post irradiation methods. We determine the spectral and the spatial trap distribution in the oxide of four hardened and unhardened devices. One unhardened device seems to present a trapping behavior close to the SIMOX buried oxide one.
