SINF is an ASCII map file format and TEL P8 is the binary format for the family of probers build by Tokyo Electron Limited. The TEL P8 prober requires two input files: a wafer file and a lot file.
Start the program by double clicking on the WaferMap Convert shortcut. The main dialog should open.
Now use the drop downs to set your input format to SINF and your output format to P8.
Use the Input | Browse... button and navigate to the file you wish to convert. In this example, the SINF files have the suffix .sinf but this is not always the case. Always open your file with text editor and verify that the syntax matches the SINF syntax.
The dialog should now look like this:
Now click on the Scan button.
A new dialog should appear:
One will see a number of parameter values that have been obtained from the input file and there are some that need to be filled in by the user - either because the input file does not support these parameters or because they should be present in the input file but are missing.
For example, SINF does not have a parameter for wafer diameter. So the user should enter it.
SINF does have a parameter for the step size, but the file we are using in this example is missing the size or step parameter along with the units of the step size.
Based on external information, the user updates the parameters and also the mapping from SINF bin codes into "Quality" for the TEL P8. Unlike most map files, the TEL P8 only has: PASS/FAIL and SKIP. It does not make use of the NULL bin either so it is important to specify which bin is NULL so that the output won't include these devices.
If the Quality field says Unknown, double click on it and select from the drop down the correct Quality property such as Pass, Fail, Skip or Null.
Our final configuration dialog will look like this once the user has made all the changes.
Now press Convert to produce the P8 wafer file and lot file.
In the directory there are now two new files.
The new files are binary - one cannot view or read them with a text editor.
The file called LOT.DAT contains LOT information which includes the lot name, the wafer number, the wafer diameter and the stepping information.
The file called m53737-01a0.DAT is the wafer file containing the bin codes for the devices on the wafer.
Two files created from SINF.
