Abstract:
A semiconductor factory automation (FA) system, comprising:a common communication line; a plurality of semiconductor processing means coupled to said common communication each for carrying out a predetermined semiconductor process at an operating mode having a full automation mode and sending a process completion signal after the predetermined semiconductor process has been completed, wherein the predetermined semiconductor process is applied to a lot of semiconductor wafers; an operator interface means coupled to said common communication line for receiving operating mode information of each semiconductor processing means and the operating mode information changed by an operator; a storing means coupled to said common communication line for storing the operating mode information changed from said operator interface means; a creation means coupled to said common communication line for creating a queue in response to the process completion signal; a control means coupled to said common communication line and responsive to the queue for checking the operating mode information of each semiconductor processing means stored in said storing means; and a transportation means for unloading the lot of semiconductor wafers from each semiconductor processing means in response to the queue received from said control means, wherein said control means inactivates said transportation means by interrupting a transmission of the queue to said transportation means if the operating mode information of each semiconductor processing means stored in said storing means is not the full automation mode.
