Popis: A new definition of L eff which agrees well with electrical measurements using the channel resistance method is proposed, based on numerically simulated surface potential. Using the L eff definition, the physics underlying the fact that L eff can be considerably longer than the metallurgical channel length L eff is explored, and the independence of L eff on substrate bias V sub is clarified. The gate bias dependence of L eff in LDD MOSFET is clearly reflected by the proposed L eff definition.
