Wafers produced by UMC may be accompanied by probe data using this map format.
UMC indicates UMC map file format X410268 lot ID X410268-09 lot ID/Wafer Number X410268_X410268-09.UMC file name? ROWCNT 148 number of rows COLCNT 147 number of columns PASBIN 1 bin code for PASS devices NODI .,X bin codes for no die (comma delimited)
The header is immediately followed by the map. The map uses a single ASCII character with no spaces between bin codes and a CR/LF at the end of each row.

We don't have a full specification on the UMC wafer map format so are working only from sample data.
