Abstract

In one aspect a factory automation system for a wafer fab is provided. The factory automation system comprises: a manufacturing execution system for providing lot information; a material control system for providing dynamic traffic information; an automated material handling system for providing static route information; and a real-time dispatching system to select a destination and a route for a wafer carrier in response to a transfer request. In another aspect a method of transferring a wafer lot within a wafer fabrication facility using a factory automation system is provided. The method comprises: receiving a transfer request to move the wafer lot from a first position to a second position within the fab; obtaining lot information, dynamic traffic information, and static traffic information; using the information to select a route between the first position and the second position; and executing the transfer using the selected route.

Description

technical field [0001] The present invention relates to a factory automation system and related methods, in particular to a system and method for realizing factory automation in a wafer manufacturing plant. Background technique [0002] The manufacture of semiconductor devices involves the performance of a series of manufacturing steps. These manufacturing steps are completed in a specific order and usually within a specific period of time using various high-tech products and measuring equipment. The main function of the wafer material flow system in a wafer manufacturing plant (or "fab") is to transfer wafers to each device at the correct time point, and to track the position and status of wafers throughout the manufacturing process. [0003] Automated material handling systems (AMHS) are used in wafer fabs to perform automated functions more efficiently, consistently, and safely than can be accomplished by manual means. Although the progress of semiconductor dimensions fr...
