A technique to measure the lateral distribution of both interface traps and trapped oxide charge near the source-drain junctions in MOSFETs is presented. Its basic principle is described. This technique derives from the charge-pumping method, is easy to implement, and allows ready separation of the interface-trap and oxide charge components. Examples are shown for hot-carrier stressed MOS transistors.<
