Abstract :
This report describes a material management system with a function of estimated number based on MES. It is difficult to ensure adequate quantity of the required stock for each material in a development fabrication, because of the change of process flow and materials. Using the method of estimated number which utilizes the number of wafers which will be used in a production control system, we have been able to ensure adequate quantity of the required stock for each material and take measures for logistics or cost reduction
