ICS File Structure

ICS stores data and setups in a database file located in your W:\data folder (the W: drive should be automatically mapped when you log into the PC workstation). This folder initially contains all of the test setups for testing both the commercial devices and your wafer. If the W:/data folder is not there, ask your TA to help you map it.

Finding and Opening Test Setups

To view the setups, start ICS and select Database Search/Report under the File pull down menu. A window named File Manager – Search Criteria opens with six Attribute pull down boxes. The choices for Attribute #1 will be:

Attribute #1:

Select Tutorial for Attribute #1 in ICS.

Once Attribute #1 is selected, Attribute #2 will display the appropriate devices. The choices for Attribute #2 will be (with Tutorial selected):

Attribute #2:

Select 2N2222 BJT for Attribute #2 in ICS and click search.

A new window named File Manager Browser will open containing a list of all setups matching the search criteria.

Select 2N2222 BJT and click on Open.

The File Manager will close, and all of the test setups for the BJT will open in the main window (they will be minimized).

Saving Test Setups

At this point save the 2N2222 BJT setup.

To save, use the Save As option under the File pull-down menu item.

  • Type your NetID in Attribute #3.
  • In Attribute #4 type Data1.
  • Click on OK to save the data with your personalized attributes.

Multiple Test Setups for the Same Device Type

Attribute #4 allows you to separate different sets of data. If three sets of data are needed for the 2N2222 BJT, two more files will need to be created. The data will be saved as follows:

  • Tutorial : 2N2222 BJT : NetID : Data2
  • Tutorial : 2N2222 BJT : NetID : Data3

You can create these in the same way as Data1.

Perform the following tests in order:

  1. MOS Capacitor

  2. PMOSFET

  3. pn Diode

  4. BJT
