The Ultrasort 408 is a dual-robot semiconductor wafer mapping and sorting system originally manufactured by Irvine Optical. Its four-cassette architecture handles 125, 150, and 200 mm wafers and supports lot mapping, identification, sorting, and transfer operations. Manufacturer documentation specifies throughput up to 800 wafers per hour

Ultrasort 408 and Ultrasort 408 SC Are Distinct Models
The manufacturer documented the Ultrasort 408 SC as a separate SMIF-equipped sibling. Features unique to the SC version must not be attributed to a bare UL408 identifier without suffix or label evidence.
Ultrasort 408Four-cassette mapping and sorting system for 125, 150, and 200 mm wafers.
Ultrasort 408 SCSeparately named four-cassette SMIF sorting system documented for 200 mm wafers.
Applicability boundaryDo not assert SMIF-pod compatibility, the SC minienvironment, 26-slot upgrade capability, or other SC-only features for UL408 without complete model-label evidence.
