From wafer maps and engineer notes to an optimized schedule.

Two hundred wafer lots are queued for eight lithography scanners at the start of a 12-hour shift. Scheduling them requires reading each lot’s defect map image, measurements, and shop-floor notes to decide whether it is safe to run and which scanner it can use. Engineers can’t review 200 lots in time, and schedulers can’t read images or free text. Bivia evaluates every lot in seconds, holds the risky ones back, and schedules the rest across the eight scanners.
