    • PURPOSE:To continuously process a plurality of batches according to a wafer processing sequence without causing wait time or non-operating time between the batches. CONSTITUTION:An apparatus and method for controlling a vertical furnace comprises a batch cassette exchanging function 14 which replaces a processed batch cassette with an unprocessed batch cassette as soon as processing of one batch is completed, a processing control function 13 for starting next batch processing as soon as cassette replacement is completed and a process recipe reservation function 15 for storing in a memory wafer processing sequence names for making correspondence between a wafer processing sequence which is different for each of the batches and each batch whereby a plurality of batches can be continuously processed according to the wafer processing procedure.

    • PURPOSE:To provide information showing which lot is to preferentially be produced for manufacturing a semiconductor element by means of the production system of small scale many kinds. CONSTITUTION:A work plan 1 obtained by collecting information when the lot starting manufacture is to pass through respective processes is decided by considering the capacity of a manufacture process. A computer screen is used for deciding which work of the lot is to be proceeded among the elements which are not started yet by using a line and a manufacture equipment, which are not operated, as to the unstarted elements existing in a certain work process. Namely, efficient flowing information 3 is provided based on difference information 4 between a work plan master 1 and the progress advance degree of actual lot 2. Thus, a worker can instantaneously decide the lot and the manufacture equipment, with which the lot is proceeded by plan difference information 4 and work priority ranking information 5. Consequently, the system is a presently efficient method with which the production system of small scale many kinds is executed, and it is considerably efficient in a manufacture scene.
