Unison doesn't automatically add WIR, WCR, and WRR records into STDF file. To enable it, you need to add Wafer Descriptor object in the test program. To do this, follow the instructions below:
- In
Optool menu, go to Tools > Wafer Map, the WaferMapTool will
open.
- In
the WaferMapTool, create Wafer Descriptor object. In my example below, I
named the object “PutWaferDescriptorObjectNameHere”
- In
the WaferMapTool menu, go to Edit > Edit Wafer Description…, the
Edit Wafer Description Tool will open
- Put
all the necessary values in the fields as shown below. Click OK
- Now
that you have the Wafer Descriptor object. Let’s make it active. In
OpTool menu, go to Setup > Active Object > Wafer…, select the
Wafer Descriptor you created. In my case it’s the
“PutWaferDescriptorObjectNameHere”.
- Don’t
forget to SAVE your program!!!
- Now
from here on, as long as you use CURI driver that is for prober/wafer
testing, you should generate WIR, WCR, and WRR in your STDF file.
