Abstract: A method of processing management information is disclosed that comprises the steps of: receiving electronic information into a receiving server; identifying a sender corresponding to each transmission contained within the received electronic information; determining the number of received transmissions contained within the received electronic information; and performing a first priority ranking of the received electronic information based upon sender criteria and the number of received transmissions. An information processing system for practicing the management information processing method is also disclosed.

Abstract: This invention is to realize a final circuit by wiring only the top layer depending on the individual circuits, by fabricating a master slice in the step of up to forming plural semiconductor elements such as transistors on a semiconductor substrate, forming a lower layer of versatile wiring pieces thereon, and forming contact holes thereon. In this way, since the step just before formation of the top layer wiring can be carried out regardless of the features of individual circuits, preliminary mass productions are possible, and final products can be completed only by forming the wiring of the top layer depending on the requirements of the users. Accordingly, it is applicable to a wide variety of products, and the term for development and manufacture can be tremendously shortened.
