opt_ex23 : ASM-HEMT Symmetric GaN HEMT Model Extraction
Requires: Utmost IV, SmartSpice, SmartView
Minimum Versions: Utmost IV 2.4.0.R, SmartSpice 4.32.0.R, SmartView 2.34.0.R.
This example describes how to extract an ASM model using a single geometry, symmetric HEMT device.
The project file opt_ex23.prj and the data file opt_ex23.uds for this example should be loaded into your database. When opened, the project will look as shown in opt_ex23_project.png .
Preliminary information
The ASM model allows independent parameters to describe the source and drain region resistances and their bias dependencies. In order to consider symmetric devices with the same parameter values for drain and source, respectively, one can assign two model parameters to the same netlist parameter and optimize the netlist parameter instead: opt_ex23_model_card.png and opt_ex23_netlist_parameters.png .
Note that the self-heating model is disabled for the first 7 steps. This is done by setting the SHMOD model parameter to 0: opt_ex23_model_card.png . The self-heating model will be turned on at the beginning of Section 8.
This example uses depletion mode HEMT devices. In order to better display the ID-VG plots of such devices, one needs to edit the preferences: opt_ex23_edit_preferences.png and set the X Axis Direction to "By Sweep" in the Viewer preferences: opt_ex23_preferences_x_axis.png .
The optimization sequence, which automates the parameter extraction, is divided into nine sections. The objective of each section is to isolate a device characteristic and then to optimize only those model parameters which account for this device behavior. Some model parameters are optimized in multiple sections for better fitting.
Before starting the optimization sequence, the following device parameters are defined in the model library.
- TBAR: Thickness of the AlGaN Layer
- LDG: Drain side access region distance
- LSG: Source side access region distance
- TNOM: Nominal (room) temperature
Section 1 : idvglin_rt
This section performs a preliminary extraction of the threshold voltage for the wide and long channel device, using the drain current versus gate voltage characteristic in the linear region and at room temperature. The extracted value is stored in the VOFF model parameter, as shown in opt_ex23_01.png .
Section 2 : idvglin_rt
This section optimizes the parameters for wide and long channel devices. The data in this section is the drain current versus gate voltage characteristic in the linear region and at room temperature. The following model parameters are extracted.

- UA Mobility degradation coefficient
