3 Verifying System Functionality
This completes the functional verification procedure.
15 For systems with the
Agilent 4284A precision
LCR meter, open the
junction capacitance
model (juncap.mdl) in
IC-CAP.
a From the IC-CAP/Main window menu bar,
choose File > Examples... .
b In the Directories list of the File Open dialog
box, double-click on the directory
.../examples/model_files.
c In the Directories list of the File Open dialog
box, double-click on the directory
.../model_files/diode.
d In the Files list of the File Open dialog,
double-click on juncap.mdl.
This opens the File Open dialog box.
This opens a list of model files.
(Scroll the list, if needed.) This displays
a list of modeling files in the Files list of
the File Open dialog.
This opens the juncap model window.
The juncap model window contains tab
folders used to interact with the model
data.
16 Select the DUT/Setup. a Select the DUTs-Setups tab.
b Click the area > cv setup.
This opens the capacitance vs. voltage
setup.
17 Set the LCR meter
instrument options.
a Select the Instrument Options tab.
b Highlight the Cable Length variable and
enter 2.
This sets the cable length in the LCR
meter instrument options.
18 Calibrate the LCR meter. a On the 16048D test leads, connect one tee
between the H
pot
and H
cur
connectors.
b Connect the other tee between the L
pot
and
L
cur
connectors. Select the
Measure/Simulate tab.
c Select Calibrate.
d Follow the IC-CAP prompts.
This performs a calibration on the LCR
meter.
The BNC tee part number is 1250-2405.
19 Measure the open circuit
capacitance.
a Select Measure.
This measures the open circuit
capacitance.
20 Observe the results a After the calibration is complete, observe
the plot.
b Rescale the measured result (displayed in
red) cap.m.
The measured result should be less
than ±10E-15 farads.
* To familiarize yourself with the IC-CAP software, refer to the first three chapters of the Agilent IC-CAP 2004 User’s Guide, model number
85190D.
To save this hardware configuration: on the IC-CAP main menu bar, choose File > Save As and enter a filename, for example
config1.hwd (the file suffix must be .hwd).
