Abstract

PURPOSE:To reduce the number of lot by setting process treatment conditions for every semiconductor wafer thereby considering only one lot even when a plurality of conditions are set in one process. CONSTITUTION:As to processes from 1 to 4, conditions from 1 to 4 are set as process treatment conditions for each process irrespective of the number of wafers. As to the process 5, the number of the process treatment conditions is designated as 3 and respective conditions are established for each wafer: the process treatment condition 5a is set to a wafer No.1, the process treatment condition 5b is set to a wafer No.2, and the process treatment condition 5c is set to a wafer No.3. As to the processes from 6 to 9, the process treatment conditions 6-9 are set for respective processes irrespective of the number of the wafers. As a result, such process conditions can be set as the process 1 to the process 9 are considered as one lot (Lot-A).
