ABSTRACT:
The present disclosure provides an inventory tracking method for use with semiconductor product. The method can be used to track wafer lots transferred from a front end such as a fabrication (fab) facility, to a back end such as a wafer circuit probe facility. The method includes tracking a lot of wafers being sent to the back end facility and receiving a status report from the back end facility. The status report is compared to a predetermined criteria, and the lot is designated as a first type, such as slow moving, if the status report fails to meet the predetermined criteria. A payment plan is then associated with the lot due to it being designated as slow moving.
