Process domains have different physics
Deposition drift, anneal response, transfer mechanics and binning economics do not share a loss function. Forcing them into one model buries the signal that matters.
AI Agents
Each agent owns a process domain and is measured on a fab metric. The orchestrator makes sure they do not optimise against each other.
Agents trained on real display-process signals
Design
Beat 01
Deposition drift, anneal response, transfer mechanics and binning economics do not share a loss function. Forcing them into one model buries the signal that matters.
Beat 02
Each agent maps to a team that already owns the metric, so an override has an obvious owner and a training label has an obvious source.
Beat 03
A deposition correction that helps uniformity but costs throughput is a fab decision, not a model decision. The orchestrator makes it explicit.
Beat 04
An agent can graduate on its own evidence. Mura classification may be trusted long before transfer control is.

Orchestration
The same path every time, whether the outcome is a suppressed nuisance call or a recipe change.
Step 1 of 6 · sense
Domain agent reads its signals from the perception layer.
Step 2 of 6 · propose
A scoped action with a predicted effect and a confidence.
Step 3 of 6 · arbitrate
Competing proposals are weighed against yield, ramp, scrap and throughput together.
Step 4 of 6 · validate
The proposed action is simulated against panel and line state.
Step 5 of 6 · gate
Shadow logs it, advisory routes it, graduated autonomy executes low-risk actions.
Step 6 of 6 · record
Signed record with evidence, model version and approver.
The seven
Holds emitter-stack and TFT layer uniformity across the whole mother glass by closing the loop between chamber telemetry, overlay metrology and recipe write-back.
Stabilises threshold voltage and mobility across the panel so backplane variation never becomes visible non-uniformity at cell test.
Separates real large-area non-uniformity, sub-pixel opens and shorts, particles and stains from the nuisance signals that swamp inspection queues.
Optimises mass transfer and repair — the yield ceiling on microLED — by learning placement, bonding and repair outcomes emitter by emitter.
Coordinates robotic panel and cassette movement so large, fragile substrates move without breakage, particles or queue stalls.
Runs aging, test and binning decisions with the demand mix in view, so grade calls maximise value instead of defaulting to the safest bin.
Turns every excursion into a shorter ramp for the next product, compressing the manual tuning cycle that eats new-model margin.
Accountability
If an agent cannot be measured on something the fab already reports, it does not ship.
| Agent | Primary metric | Owning team |
|---|---|---|
| deposit-and-pattern | Uniformity within window / rework | Process integration |
| tft-and-anneal | Vth spread / array-test yield | Array process |
| mura-and-defect | False-call rate / escape rate | Quality and inspection |
| microled-transfer | Transfer yield / repair cycles | Process integration |
| panel-handling | Breakage and particle events | Equipment engineering |
| age-test-and-bin | Recovered value per panel | Manufacturing operations |
| yield-and-ramp | Weeks to target yield | Yield engineering |
Human-in-the-loop
Engineers are not an obstacle to autonomy; they are the training signal that makes it possible. Every override is captured with its reasoning and flows back into the model that made the call.

Under the hood
This is the loop the orchestrator runs, condensed. In shadow mode every line still executes — only the write-back is withheld.
cycle panel=G6F-118422 mode=advisory
mura-and-defect 3 calls → 1 real, 2 suppressed
deposit-and-pattern drift +0.4nm/h chamber 3

orchestrator: correct deposition, hold throughput

Where agents connect
Voices from the line
“We do not lose panels because nobody is watching. We lose them because the signal that mattered was buried under a thousand nuisance calls.”
“Ramp is the whole game. If a new product takes two quarters of manual tuning, that is two quarters of margin we never get back.”
“Transfer yield is our ceiling on microLED. Every dead emitter is a repair cycle or a scrapped backplane.”

The economics
Emiteon is priced and evaluated on the numbers a fab already reports. These are design-partner targets for the first twelve months of deployment.
Figures marked as targets are design-partner objectives, not audited results. Company operating status, customers and outcomes are [ASPIRATIONAL] until independently verified.
FAQ
Through three gates. Shadow mode observes and predicts with no write-back; advisory mode recommends recipe, transfer and binning moves that a process-integration or yield engineer approves; graduated autonomy releases low-risk deposition, anneal and transfer control once measured accuracy and twin validation clear the bar. High-impact decisions stay human-in-the-loop.
Reducing false calls is the wedge, not a side effect. The mura-and-defect agent is trained on true-versus-false-call labels from your own inspection history, so it separates genuine large-area non-uniformity, sub-pixel opens and shorts, particles and stains from nuisance signals, and every call is traceable to the evidence behind it.
Per-tenant isolation with recipes, panel designs and defect images scoped to your tenant, encryption in transit and at rest, SSO/RBAC, an immutable yield/quality-grade audit log and an on-prem or air-gapped option. Fleet learning shares model improvements, never your recipes.
