Lateral profiling of oxide charge and interface traps near MOSFET junctions

A technique for measuring the lateral distributions of both interface traps and trapped oxide charge near the source/drain junctions in MOSFETs is presented in detail. This technique derives from the charge pumping method, is easy to implement, and allows ready separation of the interface-trap and oxide charge components. Some illustrative results are given. The various issues involved in its implementation and its practical limitations are discussed.<
