  • Numerical analysis
  • Causal Inference

Defect factor analysis using Transfer Lasso

Reduces the time and effort required for regular factor analyses, and identifies the essential factors of defects.

  • In periodic analysis of defective factors, utilizing the results of a previous analysis eliminates unnecessary repeated inspections.
  • Reduces the effects of nonessential factor changes (noise).
  • Used in Toshiba’s semiconductor manufacturing facilities.


  • Defect factor analysis in semiconductor factories
  • Defect factor analysis in other plants

Benchmarks, strengths, and track record

  • Dramatically reduces the time required for detailed investigations of analysis results at semiconductor factories and other plants.
