The IDScoped™ system automatically aligns wafers and reads wafer IDs in less than 40 seconds in cassette. The IDScoped™ outperforms any currently available wafer ID reader with its production-proven, constantly improving design and concept. The system detects and communicates wafer presence/absence, slot location, and IDs to the FAB host. It is ideal for creating wafer lots at the introduction into the FAB, catching mixed wafers, tracking wafers, lots, and verifying the quality of ID marking at the wafer foundry. The system can be programmed to read all or only user specified slots locations. Other options include backside ID reading. The very compact, desktop reading engine uses an under desk controller to minimize required FAB space. Models are available for 125, 150, and 200mm wafers.
