  • Publication number: 20240377830
    Abstract: A mobile stocker described herein is configured to be easily installed and relocated to various locations in a semiconductor fabrication facility. The mobile stocker is capable of being programmed with, and/or autonomously learning, the layout of a semiconductor fabrication facility, and automatically relocating to a new location based on the layout using a navigation system. Accordingly, the mobile stocker is capable of being flexibly relocated in the semiconductor fabrication facility to dynamically support changes in demand and production capacity. Moreover, the capability to quickly assign a location identifier to the mobile stocker and to automatically interface with transport systems in the semiconductor fabrication facility reduces downtime of the mobile stocker, which increases productivity in the semiconductor fabrication facility.

  • Publication number: 20230343621
    Abstract: The present disclosure is directed to a stocker utilizing one or more storage carriers to optimize the utilization of a storage compartment within the stocker. The stocker includes one or more storage towers each including one or more shelves that may be moved from a closed position to an opened position by being pulled outward by a hook of a forking structure. This forking structure is configured to lift up a corresponding storage carrier off the shelf to be transported to a storage carrier load port to position one or more workpieces or toolpieces within the storage carrier, which is then transported back to the corresponding shelf for storage. The utilization of the forking structure along with the pull out shelves allows for a large number of storage carriers to be stored within the storage compartment of the stocker.

    Abstract: A support member system is described for association with an overhead transport system. The support member system provides a safety feature to the overhead transport system by which the overhead transport system is able to avoid damage to wafers that are contained within a wafer cassette that is unintentionally released by the overhead transport system. The support member system is able to prevent such released cassettes from impacting the ground or tools located under the overhead transport system. The support member system targets wafer cassettes that have dimensions which are different than the dimensions of wafer cassettes for which the overhead transport system was originally designed to transport. Stocker systems for receiving, storing and delivering different types of wafer cassettes are also described.

  • Publication number: 20220348415
    Abstract: A system and method for rail management of an overhead transport (“OHT”) system of an associated automated material handing system (“AMHS”) that includes a controller in communication with the OHT system, including vehicles traveling on rails of the OHT. The rail management system also includes a turntable located on a portion of the OHT and equipped with a set of fixed rails. Upon receipt of a request to rotate the turntable from a first run-through direction to a second run-through direction, the controller engages at least one stopper sensor located near the turntable. The controller then directs the turntable to rotate from the first run-through direction to the second run-through direction. After completion, the controller disengages the at least one stopper to enable vehicles to travel directly in the second run-through direction.
