Smart Fab Supervision for Workforce Efficiency
Proliferating fab data creates new operational challenges.
Semiconductor manufacturing continues to grow in complexity, and with it, the volume of data generated across MES, equipment, automation systems, and planning tools. While this data is vital to factory performance, its scale and fragmentation make it increasingly difficult to translate into timely, coordinated action. Traditional reporting models rely heavily on experts’ interpretation; however this approach is less suited to the speed and cross-functional alignment required in 24/7 operations and the industry’s push to improve responsiveness without expanding headcount.
Recognizing this challenge, INFICON partnered with STMicroelectronics to rethink how fabs interact with operational data. The goal: Convert raw data into timely, role‑specific insights that directly support anomaly detection, issue resolution, and overall workforce efficiency.
A Joint Effort to Transform Raw Data into Actionable Insight
This collaboration led to the development of Impact Manager, a smart factory supervision and control room application built on digital twin technology from INFICON. Impact Manager continuously monitors factory KPIs and operational conditions, automatically identifying current and emerging anomalies such as tool downtime, bottlenecks, lot holds, queue time risks, and AMHS disruptions.
Each event is classified, prioritized, and assessed for factory impact before being translated into actionable workflows. Tasks are automatically routed to the appropriate owners, tracked through resolution, and supported with full event histories and contextual guidance. Role‑specific views ensure every user sees only the information relevant to their responsibilities, enabling faster and more effective decision‑making.
A New Model for Smart Fab Supervision
The innovation behind the system represents a shift from passive reporting to active factory orchestration. Impact Manager introduces:
- Automated detection and prioritization of 100+ anomaly types across equipment, material flow, and operational KPIs
- Centralized real-time factory supervision with integrated workflow orchestration
- Role specific data delivery tailored to ensure users receive insights relevant to their decisions
- Embedded expert knowledge for investigation steps and action plans to accelerate resolution
- Built-in foundations for agentic AI, including proactive diagnostics, root‑cause analysis, recommended actions, and future autonomous execution
This marks a move from simply presenting data to guiding actionable responses, supporting the long‑term vision of AI‑assisted and ultimately lights‑off fab management.
Impact Manager is designed not only to solve today’s supervision challenges but also to enable future automation. The combination of anomaly intelligence, workflow orchestration, and expert‑knowledge capture creates a natural pathway toward fully AI‑driven decision support and action execution.

Early Results Show Clear Efficiency Gains and Strong User Adoption
Development on Impact Manager began in 2024, with the first operational release delivered in March 2025. Since August 2025, the system has served as the primary real‑time support engine for an STMicroelectronics control room.
Early results indicate:
- Improved operator efficiency through automatic issue prioritization
- Faster response and resolution times through structured workflows
- Clearer visibility into both current and future risks
- Strong user adoption supported by an intuitive interface
- A scalable architecture planned for deployment to additional sites in 2026
Both INFICON and STMicroelectronics report encouraging early efficiency gains and see significant potential for expanded impact as AI‑driven capabilities continue to advance.
