ABSTRACT
The PSP model [1], a generalized Surface-Potential
(SP) model, has been chosen to be an industry standard
for the next generation, 60nm, technology. In order to
include quantum effects within surface potential models
we use asymptotic analysis techniques [2], [3] applied to
the the Density-Gradient equations [4]. Our quantum
modified surface potential (SP) results from the ability
to obtain a first integral of the Poisson equation.
Keywords: Surface Potential, Density Gradient, Quan-
tum corrections, asymptotic methods
1 The Quantum Problem
For MOSFETs, the ratio of the maximum channel
dopant concentration to the intrinsic level is normally
very large, therefore following [6], a large parameter
