Channel length modulation CLM.

Due to its physical nature and its built-in geometry dependence, the prediction of device behavior of advanced devices based on the parameters of the existing process is possible. The routines of this release refer to version 3. Channel length modulation CLM. Substrate current induced body effect SCBE. As a further improvement, one set of bdim3 parameters manial the whole range of channel lengths and channel widths of a certain process that can be used in circuit designs.

The extraction routines are based on the BSIM3v3. Due to the physical meaning of many model parameters, the BSIM3 model is the ideal basis for the statistical manua of process fluctuations. Therefore, you must be sure that you use the same version of BSIM3 in both your simulator and your extraction tool.

Since this channel length is no longer state-of-the-art for modern MOS devices, the model has been adopted several times to model effects not present in devices with greater channel lengths. The latest release, BSIM3v3.

The model equations used are mainly the same in those versions. The first three versions have differences in some model parameters, and the model parameter sets are not compatible. BSIM3 is a physical model with built-in dependencies of important device dimensions and process parameters like the channel length and width, the gate oxide thickness, substrate doping concentration and LDD structures. Therefore, no or only a minimum of optimization is needed to get a good fit between measured and simulated device behavior.

The model equations used are the same in those versions.

Short channel capacitance model. Substrate current induced body effect SCBE.

The following example of the parameter UC, which is a part of the mobility reduction, demonstrates the problem: The latest release, BSIM3v3. Drain induced barrier lowering DIBL. BSIM3 is a public model and is intended to simulate analog and digital circuits that consist of deep submicron MOS devices down to channel lengths of 0.

As a further improvement, one set of model parameters covers the whole range manuxl channel lengths and channel widths of a certain process that can be used in circuit gsim3. Due to its physical nature and its built-in geometry dependence, the prediction of device behavior of advanced devices based on the parameters of the existing process is possible. Due to the physical meaning of many model parameters, the BSIM3 model is the ideal basis for the statistical analysis of process fluctuations.

It can easily be recognized, that UC has quite different values in both equations.

It can easily be recognized, that UC has quite different values in both equations. Vertical and lateral non-uniform doping.

Drain induced barrier lowering DIBL.

Temperature dependence of the device behavior. The extraction routines are based on the BSIM3v3.

Mobility reduction due to vertical fields. In BSIM3v2, the effective mobility eff was calculated according to the following formula: Therefore, you must be sure that you use the same version of BSIM3 in both your simulator and your extraction tool. See References for details. The first three versions have differences in some model parameters, and the model parameter sets are not compatible.
