Patent ID: 7260444

Claim:
A real-time management method for manufacturing management and yield rate analysis integration, comprising: collecting a plurality of yield rates and inline QC parameters relating to wafer products in a predetermined period; summing and averaging the yield rates for a historical yield rate; selecting multiple representational inline QC parameters; implementing a statistical process, comprising: determining whether at least one extreme value exists in the representational inline QC parameters; if no extreme value exists, determining whether at least one collinear parameter exists in the representational inline QC parameters; and if no collinear parameter exists, determining whether residual analyses relating to the statistical process satisfy normal distribution; if the analysis result satisfies normal distribution, selecting multiple optimum inline QC parameters from the representational inline QC parameters; calculating weights of each optimum inline QC parameter; and calculating a predicted yield rate according to the historical yield rate, weights, and a plurality of measurement and target values relating to the wafer products.
