NLDD is a N-type lightly doped drain (implant layer) for E-field reduction @drain or source site especially for general submicro process.
; K, Q$ X$ i- ~, z& b' n0 x! p, MNDD is a N-type double diffusion drain (implant layer for current technology) for E-field reduction @drain or source site (depend on asymmetric or symmetric device structure) especially for high voltage process. No special layout concern, just follow DRM.
