Abstract
A wafer ID optical sorting system includes an auto-ID reader, a manual-ID reader and a conveying device, operation of which units is controlled by a monitoring system. The auto-ID reader, connected to the monitoring system, can automatically read and identify an ID and allows the ID to be displayed on the monitoring system. The manual-ID reader, connected to the monitoring system, can fetch the ID image and allows it to be displayed on the monitoring system. The conveying device, connected to the monitoring system, can move the auto-ID reader and the manual-ID reader.
