Fab Bottleneck Radar
A playful semiconductor dispatch desk for rehearsing WIP pressure, tool uptime, hot-lot chaos, yield drift, and the one calm action that keeps the shift moving.

Adjust the shift assumptions. The radar turns messy fab pressure into a simple dispatch posture and copyable handoff.

Litho queue
The tiny wafer map exaggerates drift and hot-lot pressure so the constraint feels visible before the dispatch meeting starts.
WIP plus drift that deserve human attention

Fab Bottleneck Radar · EUV queue squeeze (2 nm pilot line) Regime: AMBER QUEUE — Freeze low-value expedites and swarm the constraint. Constraint: Litho queue. Dispatch rule: cap hot lots to the top 3 revenue-critical wafers; protect uptime with no recipe experiments this block. First hour: move one engineer to the constraint, publish a WIP cap, and re-check yield drift before the next lot wave. Local demo only — no MES, secrets, or factory systems connected.
