ABSTRACT:
An Intelligent Data Multiplexer (“IDM”) can be used to interface a plurality of host computers with a semiconductor manufacturing tool. In one embodiment, the IDM has a plurality of host-side ports configured to receive messages from each of the host computers interfaced with the semiconductor manufacturing tool. The IDM also includes a multiplexer configured to multiplex the messages received from the host-side ports. To process possible conflict messages from the host computers, the IDM has a conflict resolve module. The messages are then delivered from the IDM to the semiconductor manufacturing tool through a tool-side port used to connect the semiconductor manufacturing tool to the IDM.
