Abstract

The operation of a semiconductor fabrication facility may be automated to enable efficient assignments of lots to specific process tools or entities. This may involve the use of an algorithm which may have aspects which are common across various process areas within the fabrication facility. However, the algorithm may be customized to meet the needs of specific process areas.
