Abstract
The widely accepted universal dependence of N- and P-MOSFETs carrier mobility on effective vertical field E eff = (ηQ inv + Q b ) ϵ Si has been re-examined. New empirical mobility models for both electrons and holes expressed in terms of T ox, V t and V g explicitly are formulated. New empirical mobility models are confirmed with experimental data taken from devices of different technologies. It is also shown that the hole mobility of both the surface and buried channel P-MOSFETs can be unified for the first time by a single universal mobility equation, rather than two separate equations as previously thought necessary.
