AI Customer ServiceOverlap capacitance comprises two parts: (1) a bias-independent component which models the effective overlap capacitance between the gate and the heavily doped source/drain; (2) a gate-bias dependent component between the gate and the lightly doped source/drain region.
An accurate overlap capacitance model is essential. This is especially true for the drain side where the effect of the capacitance is amplified by the transistor gain. The overlap capacitance changes with gate to source and gate to drain biases.
Most to the existing methods for gate overlap capacitance characterization rely on the models of the fringing electric field (e.g. , , , , , ). In approximate analytical formulae were used for estimation of the gate overlap capacitance effect on the total gate capacitance characteristics.
The overlap capacitance changes with gate to source and gate to drain biases. In LDD MOSFETs a substantial portion of the LDD region can be depleted, both in the vertical and lateral directions. This can lead to a large reduction of the overlap capacitance. This LDD region can be in accumulation or depletion.
A numerical procedure is also described to calculate the exact overlap capacitance with fringing, using the solution of Laplace's equation. A comparison is made to check the accuracy of the analytical expression. Good agreement is found. Experimently obtained gate-source capacitance curves are described.
For CGEOMOD = 1 CGEOMOD=1, the overlap capacitors are bias-independent, as we will discuss in the end of this section. BSIM4 model. Department of Electrical Engineering and Computer Science, UC Berkeley.
