Abstract:
A production method of performing lot management on a production line of a large volume of a large variety of semiconductor wafer products, said production line having at least one of a variety of processing apparatuses, said production method including a series of processes for a lot having a number of pieces of a same semiconductor wafer product contained in a detachable unit of a carrying container as a minimum unit of production, said series of processes performed according to a corresponding semiconductor wafer product, wherein said production method comprises:processing each piece of semiconductor wafer product in a single lot for a portion of said processes to be performed on said production line, wherein the carrying container has a detachable unit for carrying the single lot, a retaining part for retaining two of said detachable units when aggregated with each other, and wherein a plurality of compartments are uniformly spaced when said detachable units are aggregated to each other and retained by said retaining means; and processing each piece of semiconductor wafer product in a group of said lots for another portion of said processes.
