Getting Started in IC-CAP

The procedures in this chapter assume the following:

    • The system has been set up and switched on according to the instructions under:
     • Agilent 8510-based system—Configuring the System Hardware in Appendix B, "Using IC-CAP with an Agilent 85122A Precision Modeling System"
     • Agilent 8753-based system—Configuring the System Hardware in Appendix C, "Using IC-CAP with an Agilent 85123A Device Modeling System"
     • Wiltron 360-based system—Refer to your Wiltron documentation
    • The calibration standards have been removed from their containers to allow them to reach ambient room temperature.
    • The IC-CAP software has been properly installed on the computer.
    • IC-CAP has been configured to recognize the system hardware, and the SMUs have been renamed as follows, based on the instructions in the appropriate chapter:
     • Performing Hardware Setup in IC-CAP in Appendix B, "Using IC-CAP with an Agilent 85122A Precision Modeling System"
     • Performing Hardware Setup in IC-CAP in Appendix C, "Using IC-CAP with an Agilent 85123A Device Modeling System"
Rename a medium-power SMU connected to the device gate as VG

Rename a high-power SMU connected to the device drain as VD

Rename the GNDU unit (which must be connected to the source) as GND.

Refer to Appendix A, "Agilent 85190A IC-CAP" for instructions on launching the IC-CAP software and opening the model file you need. The Curtice FET model file is under:

/examples/model_files/mesfet/CGaashf.mdl

Then return to this chapter and continue with the procedures here.

Before you continue with the IC-CAP procedures, make a new directory in an appropriate location in the UNIX structure, using the mkdir command, to store the data and model files that will be generated. Give the directory a name that will associate it with the devices you are going to model. Use the cd command to change to the new directory in UNIX.
