01
Invisible from the outside
Every tool runs under unique constraints. Productivity dips stay hidden in aggregate statistics — buried under the noise of standard reporting.
Solution · Semiconductor
AI-based scheduling optimization for semiconductor equipment.
A complete framework — from the productivity loss hidden inside today's tools to a learned scheduler running in production.
The Problem
Semiconductor equipment is a supercar stuck at red lights.
High-performance tools rarely run at their full physical potential. The bottleneck isn't the hardware — it's the schedule inside the tool.
02
Caused by suboptimal scheduling
Inefficient sequencing inside the tool creates repeated wait states and idle chambers that quietly erode throughput, hour after hour.
03
Beyond the reach of manual fixes
The scheduling space is too complex for humans. Rule-based heuristics cannot capture the full potential and degrade as recipes evolve.
04
Expensive to chase manually
Manufacturers already hire teams of engineers to chase productivity tool by tool. Coverage stays partial; the long tail of losses persists.
Why it's so hard
Two schedules look identical to the human eye — yet the productivity gap can exceed 20%.
Intra-tool scheduling combines recipes, chamber states, and wafer priorities into an NP-hard space with no analytic optimum. Sub-second decisions must adapt to constant recipe variability — far beyond what handcrafted rules can keep up with.

The Solution
AI-driven scheduling that learns, adapts, and optimizes in real time.
Chronoboost combines a digital-twin simulator with reinforcement-learning agents to discover the schedule that pushes each tool to its physical optimum.
Step 01
Equipment Modeling
Each tool is replicated as a high-fidelity digital twin — chambers, robots, recipes, and constraints — ready for AI simulation.
Step 02
AI Model Training
Millions of simulated runs train an optimal scheduling policy. The agent learns context-aware decisions no rulebook could encode.
Step 03
Real-Time Scheduling
The trained model issues sub-second scheduling decisions in production — fully automated, continuously refined from operational data.
Core technical differentiators
- Adapts instantly to recipe changes and process-time variability — no manual intervention required.
- Outperforms conventional rule-based and heuristic schedulers on the same hardware.
- Near-instant decisions: no throughput loss to scheduler latency.
- Continuous learning — performance keeps improving as more operational data accumulates.
The Results
From 32% to 99% of optimum — through training alone.
In our in-house digital-twin simulator, the AI agent converges rapidly toward the theoretical maximum throughput of each tool — with no changes to recipes or process steps.

The same approach generalizes to live equipment: each tool's digital twin trains a dedicated policy that captures its specific physical constraints, recipe mix, and operating context.
The Benefits
Productivity gains where they matter most — and risk where it matters least.
A software layer that maximizes the output of every tool already on the floor, with deployment characteristics designed for production fabs.
20%+ throughput uplift
Tools with significant scheduling-loss potential see real, measurable improvements without any change to recipes or hardware.
Software-only deployment
No process change, no recipe change, no hardware modification. Productivity gains land without yield risk.
Quantitative benchmarks
Know the physical optimum of every tool. Replace ambiguous productivity targets with data-grounded baselines.
Reduced engineering load
Productivity analysis and improvement become algorithm-driven — covering every tool without scaling the engineering team linearly.
Continuous learning
Performance compounds over time. The longer the system runs, the more operational data refines the scheduling policy.
Quick-to-validate ROI
Works on equipment already on the floor. Pilot to measurable gain in a relatively short window — no fab build required.
