Recently there was some work being done to upgrade a FAB. There is a neighboring fab across the street. To avoid disrupting their neighbors, the work had to be spec’d without heavy equipment, jackhammers, or large ground moving equipment. When you are dealing with nanometers of precision, even the smallest bump can ruin a batch of multi-million dollar wafers being run through lithography.
