AMHS for Semiconductor Fabs
Installing both manual and automated lifters to support OHT and OHB systems
Automated Material Handling Systems (AMHS) play a vital role in enhancing efficiency, safety, and throughput in modern semiconductor facilities. By automating the movement of materials between tools, bays, and storage areas, AMHS solutions streamline operations and improve overall fab performance.
AM Technical Solutions (AM) brings extensive experience in executing complex semiconductor facility installations within high-tech environments. We are currently leveraging this expertise to support a U.S.-based semiconductor manufacturer on a critical facility installation project designed to meet evolving production demands.
Our approach is guided by a “Right First Time” philosophy—ensuring that project requirements are met from the outset, minimizing unexpected changes, and successfully balancing cost, quality, and schedule.
Project Scope: AMHS Installation
This project focuses on the installation of a comprehensive AMHS solution across multiple bays within the semiconductor facility. The scope includes key systems such as Overhead Hoist Transport (OHT), Overhead Hoist Buffers (OHB), and Stockers.
Key activities include:
Installing AMHS track systems (rails, curves, branches, and straight sections), along with brackets, barcodes, magnets, and OHB storage locations across multiple bays
Installing both manual and automated lifters to support OHT and OHB systems
Receiving, inventorying, and installing all client-supplied materials, including tracks, lifters, and Stockers
Verifying client survey data prior to installation to ensure alignment with fab layouts and tool positioning
Providing and operating access equipment such as scissor lifts, rolling scaffolds, and gantry lifts to support installation at height
To ensure safe and efficient execution, experienced personnel and subject matter experts (SMEs) will perform all installation activities. Strict controls will be maintained over quality, cleanliness, and coordination with other trades on site.
Stocker Installation & Integration
Stocker installation is a critical component of the overall AMHS solution. A dedicated team will manage the installation across multiple levels and bay configurations. Close collaboration with the client and other trades will ensure all plans and specifications are validated prior to installation.
This coordinated effort ensures seamless integration between Stockers, OHT/OHB systems, and the overall fab layout.
Delivering a Fully Integrated Solution
By combining AMHS track systems, transport technologies, and storage solutions into a unified installation strategy, we will deliver a fully coordinated and certifiable system. This approach supports the high-throughput demands of semiconductor manufacturing while meeting stringent cleanliness and performance standards.
Our in-house design and engineering stamping capabilities ensure full compliance with industry and facility requirements. Additionally, our internal NEBB cleanroom certification expertise ensures the completed system meets all certification standards and supports long-term operational reliability.
“This AMHS installation will be instrumental in helping our client achieve their advanced semiconductor production goals,” said Robert Logston, SVP of Construction. “We are committed to delivering a fully integrated solution aligned with our ‘Right First Time’ approach—meeting all project objectives without compromise.”
