Super-hot-runs management system

摘要

Our project's purpose is to reduce the cycle time of "Push lots". Some lots must be pushed at a faster speed than normal lots. We refer to these lots as Super-HotRuns. For example: If the customer's special requirements includes, pilot lot or FAD Potential-lot,. Our project's purpose is to reduce the cycle times of "Push lots" (Superhot-runs, pilot, hot-lots) to ensure maximum customer satisfaction. According to our historical data, the cycle times of push lots were 1.0 days/layer before we started this project. We made a project goal: by reducing the C/T from 1.0 days/layer to 0.8 days/layer. We set the goal by analyzing the percentage of run, queue, hold. Then tuned a reasonable queue time SPEC to meet C/T target. Hold time reduction is also being deak with in this project. To use a team approach, and we will creat system to management push-lots. This management system includes 5 sub-systems as follow: 1. Starting announcement 2. Forecast system 3. Operating rule 4. Review system 5. Feedback system We have made great progress by using this SPReview system. Our cycle times are kept under 0.8 days/layer, and pilot lots are kept under 1.0 days/layer
