Problems solved by technology

[0011] Therefore, the substrate manufacturer must bear the temporary huge cost burden for purchasing the concentration control device, the chemical solution preparation device, and the chemical solution regeneration device, as well as various efforts and burdens involved in the operation and maintenance management after the purchase.
In addition, there is another problem that it is difficult for device sellers to earn sufficient profits unless they repeatedly find substrate manufacturers who wish to purchase devices in a limited market and sell the devices.

Abstract

The invention provides a chemical liquid management system for a substrate processing device which is most suitable for managing chemical liquid used for manufacturing a substrate to be in the optimalstate, a computing method for chemical liquid management expenses for the substrate processing device and a computing system for chemical liquid management expenses for the substrate processing device. In the chemical liquid management system for the substrate processing device, a piping provided with an accumulative flow meter connects the substrate processing device with a chemical liquid preparing device preparing new liquid of chemical liquid and a chemical liquid regenerator for regenerating the chemical liquid being used. A concentration management device measures the concentration of the chemical liquid of the substrate processing device, adding the stoste or the new liquid and regenerated liquid of the chemical liquid, managing the chemical liquid to be with the optimal concentration. The accumulative flow of the supplied added liquid is metered by the accumulative flow meter which is connected with a network directly.

Description
