Abstract
The authors present a newly invented BC412 bar code for silicon wafer identification in automated semiconductor manufacturing floor control systems. This code has been tested and has been approved to be a SEMI standard in June 1992. It is a very important technology breakthrough and expected to be used by all semiconductor wafer manufacturers. The technical details of BC412 are presented.
