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

Claim 8:
9. A semiconductor manufacturing method, comprising:
receiving, by a storage device, inputs of log data recording manufacturing operations of a series of manufacturing units of at least one semiconductor manufacturing apparatus performed on a plurality of wafers in a real-time manner; and
building a transition state model, by a control unit, based on the log data to:
analyze behaviors related to wafer transfer sequence and activities of the manufacturing operations of the series of manufacturing units based on the log data;
generate behavior attributions for the behaviors;
capture a root cause of a bad behavior based on the behavior attributions;
reproduce the bad behavior by performing a simulation based on the transition state model;
adjust a control rule of the manufacturing units according to the reproduced bad behavior; and
manufacture a plurality of processed wafers by utilizing the adjusted control rule to perform the manufacturing operations of the series of the manufacturing units.
