Abstract

Market conditions continually force the need to increase operational performance through increased equipment utilization and productivity. Fab 7 ramped a perceived full Fab by an additional 25% in order to meet a growing Flash market. The additional load on the factory incurred an unanticipated increase in Fab Throughput Time (TPT). It was obvious that a change in forecasting methodology was required. A model to forecast the TPT based on the Long Range Plan (LRP) was developed. The TPT model has increased Fab 7´s ability to more accurately predict die-out commitments. Moreover, the model increased predictability of TPT (+/-2 days) from 50% to 100%. Finally, the model has provided a business tool to evaluate factory parameter trade-offs
