A method and system for a reject management protocol within a back-end IC manufacturing
process. In one method embodiment, the present invention implements a tracking
process for a die-strip. The present invention also maintains an electronic die-strip
map database, and utilizes the tracking process to update the electronic die-strip
map database as the die-strip moves in an in-line fashion from one sub-station
to another within the manufacturing process. Information used to update the database
can originate from one or more automated visual camera systems used for quality
assurance. In so doing, the present invention categorizes the die on the die-strip
based on information maintained by the electronic die-strip map database. This
information can be used for die sorting and for die rejection. In one embodiment,
an identifying code is placed on each die strip that can automatically identify
the die-strip using the automated camera systems.
