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. Mobility reduction due to vertical fields.

mabual You can order this manual from Berkeley or you can get it over the Internet. See References for details. Drain induced barrier lowering DIBL. Temperature dependence of the device behavior. 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. Therefore, no or only a minimum of optimization is needed to get a good fit between measured and simulated device behavior.

BSIM3 is a physical model with built-in dependencies of important device manuql and process parameters like the channel length and width, the gate oxide thickness, substrate doping concentration and LDD structures. In BSIM3v2, the effective mobility eff was calculated according to the following formula: As a further improvement, one set of model parameters covers the whole range of channel lengths and channel widths of a certain process that can be used in circuit designs.

Short channel capacitance model.

The BSIM3 Model

Therefore, no or only a minimum of optimization is needed to get a good fit between measured and simulated device behavior. The following example of the parameter UC, which is a part of the mobility reduction, demonstrates the problem: As a further improvement, one set of model parameters covers the whole range of channel lengths and channel widths of a certain process that can be used in circuit designs.

You can order this manual from Berkeley or you can get it over the Internet.

The routines of this release refer to version 3. Substrate current induced body effect SCBE. 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. The following example of the parameter UC, which is a part of the mobility reduction, demonstrates the problem: The first three versions have differences in some model parameters, and the model parameter sets are not compatible.

Therefore, you must be sure that you use the same version of BSIM3 in both your simulator and your extraction tool. Vertical and lateral non-uniform doping.

Therefore, you must be sure that you use the same version of BSIM3 in both your simulator and your extraction tool. Drain induced barrier lowering DIBL. Channel length modulation CLM. The model equations used are the same in those versions. The extraction routines are based on the BSIM3v3. Substrate current induced body effect SCBE. The latest release, BSIM3v3. bsi,3

Vertical and lateral non-uniform doping. In BSIM3v2, the effective mobility eff was calculated according to the following formula: Short channel capacitance model. It can easily be recognized, that UC has quite different values in both equations. Temperature dependence of the device behavior.

Due to the physical meaning of many model parameters, the BSIM3 model is the ideal basis for the statistical analysis of process fluctuations. 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.
