Modern semiconductor fabrication plants (Fabs) leverage Fab Automation Software and controllers to optimize yield, enhance throughput, and enable intelligent process control.
Core Technologies in Smarter Semiconductor FAB
Rapid Effect adopts industry best practices and implements the following technologies that are considered essential for Smarter Semiconductor Fabs
Management & Control Systems
- FMS (Facility Management System): Centralized monitoring of cleanroom environments.
- UPW / Gas / Chemical Delivery Systems: Critical control for Ultra-Pure Water, bulk gases, and slurry distribution.
- Other Sub Systems: Acid, caustic, solvent, and chemical exhaust systems, Process water cooling, vacuum
- MES / CIM (Manufacturing Execution System / Computer Integrated Manufacturing): Controls work-in-progress (WIP) and recipe management.
- Advanced Process Control (APC) and Fault Detection and Classification (FDC)
- Automated Material Handling Systems (AMHS)
Programmable Logic Controllers (PLCs)
Industrial Grade and High Availability (HA) Controllers. Redundant SCADA and PLC architectures to ensure no single point of failure
Human-Machine Interfaces (HMIs)
SEMI E95 compliant interfaces, Redundant Servers (HA), and Engineering Workstations with Dashboards for operators to monitor and control Tools and AMHS (Automated Material Handling Systems)
Industrial Communication Networks
Protocols like SECS/GEM, Interface A (EDA), EtherCAT, and PROFINET for high-speed device interoperability. Additionally, OPC UA (Open Platform Communications Unified Architecture), which is increasingly used for secure industrial communications.
Field Devices
Cleanroom-rated Control Panels, high-precision mass flow controllers (MFCs), sensors, and RF generators for data collection and execution
Best Practices for Fab Automation in Semiconductors
Guidelines to ensure your semiconductor fab automation is optimized for yield, security, and operational excellence.
Aligning automation initiatives with yield targets and regulatory compliance.
Key Points
- Validation: Aligning automation initiatives with yield targets and node transitions is essential.
- Enhancement: Explicitly reference compliance with global standards (e.g., SEMI, ISO 9001, ANSI, IEEE, UL, NFPA) and local regulatory requirements. Ensure all systems are designed to meet the latest versions of these standards for safety, reliability, and interoperability.
- Cross-functional Collaboration: Involve Process Engineering, IT, and OT teams early; plan phased integration with legacy 200mm/300mm tools.
Project Highlights
Discover our key achievements and best solutions delivered across important projects, demonstrating our commitment to excellence at every step.
Rapid Effect was engaged to deliver a comprehensive Facility Management Control System (FMCS) for a major semiconductor expansion project in Southeast Asia. The scope covered a cleanroom expansion across multiple buildings, including fabrication, utility, and warehouse zones. The system was built on a fault-tolerant industrial Ethernet ring with redundant servers, PROFIBUS-DP modules – for the legacy systems, PROFINET modules – for new expanded facilities and high-speed I/O integration. Rapid Effect also led testing and commissioning (T&C) activities across multiple zones, ensuring seamless integration with legacy systems and new infrastructure. Functionality tests were conducted for cleanroom air systems, cold-room panels, and control valves, with manual and SCADA-based validation. Our team collaborated closely with stakeholders to align on control philosophy revisions, milestone handovers, and site instructions, ensuring compliance with cleanroom protocols, EHS standards, and quality audits
