A real-time fault detection and classification (FDC) system, which is in use with a semiconductor fabrication process having a first sub-fabrication process and a second sub-fabrication process, includes a computer integrated manufacturing (CIM) host adopting a SEMI equipment communication standard (SECS), a semiconductor tool for executing the first sub-fabrication process and generating first status data in conformity with the SECS, a non-semiconductor tool for executing the second sub-fabrication process and generating second status data in conformity with a predetermined connectivity standard different from the SECS, and a tool simulator connecting the tool simulator with the semiconductor tool and the non-semiconductor tool for receiving the first and second status data and transforming the second status data into third status data in conformity with the SECS such that the CIM host can classify the first and third status data according to a predetermined classification technique and get a control over equipment health conditions of the semiconductor tool as well as the non-semiconductor tool.
