After removing the unwanted film, the wafers are then polished, cleaned and sent back to the original customer for use as a test wafer. Significant cost savings compared to a new test wafer provides a strong incentive to use reclaim wafers in any test wafer application. KOBE guarantees surface metals, light point defects, all geometric characteristics and bulk resistivity.
All types of metals can be effectively and reliably reclaimed.
Multi-layer patterned wafers can also be processed. Customers usually store their used wafers at KOBE's warehouse and then provide a release shipment schedule. By having a fully integrated high volume factory and efficient process, we can reclaim a sizeable batch of wafers within 7-10 days. The factory operates 24 hours per day 7 days a week. In order to reclaim wafers efficiently, we ask for a minimum of 500 wafers.
