File wafer

Header File I've added carriage returns to make the data more man-readable. Annotations in italics are mine. The descriptions make sense; the values ranging from imply that the binary file is using a full byte to identify each device. What is not clear is the meaning of the first large number e. The file suffix ends in. The data is binary. I've greyed out the Wafer ID but it matches what we found in the.

XTR file If we assume that FF is a placeholder for no die, and FE is edge die as it appears from the header then we would expect to see FF followed by FE on the left and then again on the right. But it is simple enough to guess the various parameters. We call this EM Map because of the source of this map file along with the extension ". Again we found no "formal" name nor do we know what equipment likely a prober produced this output.

Notice that there is no stepping information or wafer diameter information in this format. Category : Wafers. Namespaces File Discussion. Views View Edit History.

This applies worldwide. Failing to note this could result in alignment off by 1 die in X and Y. The header appears to be identical to SINF header. As you can see, instead of 00 they this sample uses to ID each die. It is not even clear if hex numbers are supported or only since we have no spec - just this single example. However these guidelines are not necessarily formal standards. This version has only a single digit ID and it has spaces i.

This means that the program will read the header to get the number of rows. There are no spaces delimiting each die position. This map format gets its name because it has only one digit bin code and it originates from the foundry TSMC. The first few lines consist of header information. A single digit map file with a limited header.

This map format is supported only by v2 of WafermapConvert. We don't know what equipment generates this type of map data. This enables the database to actually define the ID's used for null die, skip die and test die. Other information is embedded into a header. Below you can see a sample of the row data.
