FIB modifications consist of cuts, jumpers, and probe pads.  We prefer to work from x/y coordinates consistent with the GDS (stream) file provided.   For each x/y location, please provide the metal level to eliminate any confusion should layers intersect at the given location.  Once we have your CAD navigation database, we can react quickly to changes or additions to your requested modifications by using a standardized format for describing the edit via email.  We can also work with plots to interpret the FIB modification(s).  Mirrored plots are OK, but please let us know that the plot is mirrored. Please be sure that you provide a legend for each layer represented in the plot.

FIB CAD NAVIGATION CAPABILITY:

The use of CAD navigation greatly enhances the efficiency of FIB IC modifications and is a mandatory requirement for IC designs that have more than 3 levels of metal or employ CMP.  FIB-X can create the CAD navigation database from any GDS file.  We can create both Schlumberger databases and FEI Knights databases.  FIB-X can provide a temporary FTP account to facilitate the transfer of the GDS files.  Many customers choose to send their GDS file on CD and/or DVD.
