Wafer maps are used in the back end of the IC manufacturing process to annotate the die on a wafer - the annotation may indicate whether the die is good or bad, the "grade" of the device or whether this device is a reference device.
WMVU (Wafer Map Viewer) enables an engineer to view wafer maps. It uses the same underlying libraries as WMEdit and WMBatch, but does not enable any editing or conversion.

Unlike our other products where each format requires a separate license, the WMVU license opens any format supported with Artwork's libraries. If we support the format, you are able to open and display it.
For users of WMBatch, Artwork's command line converter, WMVU is the ideal tool to verify that the command file is producing the desired output.
WMAPI based products support over 20 text, XML and binary formats. Many industry standards such as SEMI E-142, G85, IBIS and SINF. Additional formats from probers including TEL, EG and TSK. For a complete list and notes on each format please go to the Map Formats page.
