This technology file works for reading files that have been generated in the standard Xerox Cif format. This format maps pdif and pwelCont into implanted n-diffusion (two separate layers, CPI and CD), and ndif and nwelCont into just n-diffusion (CD). Since Readcif does not detect rectangle intersections, it has no way of recovering the original layers. Thus pdif and pwelCont appear as overlapping n-diffusion and p-diffusion (CD -> n-diffusion, CPI -> p-diffusion), and nwel and nwelCont appear as just n-diffusion.

This line would bloat all n-well rectangles by 4 microns. The sign of deltaRadius corresponds to the tranformation applied when writing the Cif file. Thus, BrandyCIFter would use this property to shrink by 4u while ReadCif bloats by 4u. ReadCif only performs "simple-minded" shrinks, so it is possible that you will end up with disjoint rectangles that were originally connected. Sorry.
