With nitrogen to higher yield
- May be easily retrofitted with existing systems for FOUP storage (e.g. ZFS, Stocker) without having to change the fab structure during regular fab operations
- Independent purge functionality for each nest, no gas spill / waste
- Constant gas flow during the entire storage period
- Every purge nest is individually monitored and controlled
- Avoids AMC (Airborne Molecular Contamination) and other chemical reactions
- Allows extended queue time between process steps
- Improves overall process yield
In several 300mm semiconductor fabs, more than 4,500 existing ZFS bins have been retrofitted with a Fabmatics ZFS FOUP Purge System. The solution has significantly contributed to the yield increase of the production and now allows, if necessary, higher idle times of the batches before further processing.
To date, more than 700 storage bins in stockers have been equipped with a Fabmatics MFS (Matrix Frame Storage) FOUP Purge System. The systems now available as purge-storage systems serve as WIP (Work in Progress) intermediate storage within production.
In another 300mm semiconductor factory, nearly 5,000 shelf storage places were also equipped with a Fabmatics MFS (Matrix Frame Storage) FOUP Purge System. Particularly low purge gas flow rates are used for long-term storage of end-processed wafers.
- for other wafer sizes , e.g. SMIF Pods (200mm)
- for Matrix Frame Storage (Stocker, Racks)
- for Zero Footprint Storage (OHT)
