OHT | AMHS for Semiconductor Fab. - Murata Machinery
An automated transport system that travels on the overhead track and "directly" accesses the load port of the stocker or process equipment by the belt driven hoisting mechanism. "OHT" is the abbreviation for Overhead Hoist Transport. This is widely recognized as the main transport system for 300mm FAB and next generation FABs and is currently ...
Clean Factory Automation - Muratec
Muratec’s cutting-edge cleanroom transport systems ensure seamless, contamination-free material movement. These encompass Overhead Hoist Transports (OHT), Conveyors (HTC), Tool Station Buffers (TSB), and Automated Guided Vehicles (AGVs). AGVs offer automated navigation, while OHT and HTC reduce particulate generation through elevated tracks.
Overhead Hoist Transport
The SRC350X OHT is a specialized material handling and transport solution for clean factory environments. It utilizes a belt-driven hoisting mechanism to carry FOUPs (Front Opening Unified Pods). It transports them directly from manufacturing equipment to the following processing stations or storage locations within the clean room.
The overhead hoist transport (OHT) system, which is the primary automated material handling system (AMHS) in semiconductor fab. We present the framework of the OHT management system (OMS) which effectively controls and manages more than 1,000 OHT vehicles with reinforcement learning algorithm. In
An optimal OHT dispatching system for 300 mm semiconductor ...
This paper presents the development of an optimization-based system for OHT (overhead hoist transport) dispatching with blocking effects in 300 mm semiconductor manufacturing. The OHT dispatching problem is first formulated into an integer programming problem with OHT dynamics and location constraints. We adopt the linear programming solver ...
