Abstract:
A central controller for use in a semiconductor manufacturing equipment integrates a plurality of controllers with an open architecture allowing real-time communication between the various control loops. The central controller includes at least one central processing unit (cpu) executing high level input output (i/o) and control algorithms and at least one integrated i/o controller providing integrated interface to sensors and control hardware. The integrated i/o controller performs basic i/o and low level control functions and communicates with the CPU through a bus to perform or enable controls of various subsystems of the semiconductor manufacturing equipment. A method for controlling a plurality of sensors and a plurality of control hardware for use in a semiconductor manufacturing equipment loads an application software onto a cpu board that is plugged in a bus. Sensors and control hardware are linked to electrical controllers that are mounted onto a single circuit board which occupies an address block in a memory space of the bus. The single circuit board is then plugged in the bus and the sensors and control hardware are controlled via the application software.

In one aspect, a control system includes a subsystem manager controller the operation of a respective physical subsystem for each of a plurality of physical subsystems in the fuel processor. The subsystem managers take their direction from a master control manager. In a second aspect, the subsystem managers collectively form a layer operating in conjunction with a second layer capable of interfacing the subsystem managers to their respective physical subsystems, a third layer capable of interfacing the subsystem managers with the second layer. In a third aspect, master control manager manages the operation of each physical subsystem through a respective subsystem manager, directs state transitions of the subsystem managers, and routs interaction between the subsystem managers from the master control manager.

Abstract:
An interlock system can instantly determine a controller with an abnormality in a control system of a semiconductor manufacturing apparatus in which controllers are connected through a network. The control system includes at least one apparatus controller, which controls a processing system containing at least one processing chamber which performs semiconductor manufacturing process and a conveyance system taking an object to be processed in and out of the processing chamber, and an equipment controller managing the apparatus controller. The apparatus controller and the equipment controller are communicably connected through the network. Two kinds of controllers are connected via a hard wire to transmit the status signals of those controllers to the control system so that a presence of each apparatus controller and a status of connection between the controllers can be detected without using communication through the network.

Abstract:
The feeding machine (SE) has a feed component, means for handling the individual components and a control stage (SM) for the machine's various functions. Said control stage consists of modules (PM, SM, XM, AM) for the various functions in which the individual modules form reliable, independent units and are interconnected via interfaces. The modules are controlled by a computer overriding the control stage via which the transverse connections between the individual modules also pass. The fact that the modules are autonomous provides greater redundancy in the individual functions and allows them to be individually controlled. Thus the individual functions are interdependent to only a reduced extent and faults can be easily located.
