How a Global Semiconductor Fab Reduced Equipment Downtime by 38%

How eInnoSys Alarm Management System (AMS) transformed factory efficiency, boosted OEE by 22%, and slashed wafer scrap.

• 38% Equipment Downtime Reduction
• 65% Faster Alarm Response Time
• 22% Improvement in Overall Equipment Effectiveness (OEE)
• 18% Reduction in Wafer Scrap Rate

1. The Challenge

As a leading semiconductor wafer fab expanded production, managing hundreds of disconnected equipment alarms became impossible. Critical alarms were buried under non-critical notifications, leading to undetected tool breakdowns, rising wafer scrap rates, and millions of dollars in potential production losses.

2. The eInnoSys Solution

The fab deployed the centralized, real-time eInnoSys Alarm Management System (AMS). Integrating seamlessly with SECS/GEM-enabled equipment, the solution provided instant visibility, multi-level severity tracking, and automated escalation workflows directly to the control room operators.
