Patent ID: 11860607
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H  Y | IPC G  H

Claim 17:
18. A behavior recognition device for recognizing behaviors of a semiconductor manufacturing apparatus, comprising:
a storage device configured to store log data of the semiconductor manufacturing apparatus;
a control unit cooperatively connected to the storage device, and configured to build a transition state model based on the log data to analyze behaviors related to wafer transfer sequences and manufacturing operations of a plurality of manufacturing units of the semiconductor manufacturing apparatus; and
a data transmission unit cooperatively connected to the storage device and the control unit, and configured to real-time transfer the log data of the semiconductor manufacturing apparatus from the storage device to the control unit;
wherein the control unit is further configured to perform a simulation based on the transition model to thereby reproduce an abnormal behavior of the behaviors of the manufacturing units, and adjust a control rule of the manufacturing units according to the reproduced abnormal behavior.
