A chemical supplying apparatus includes first and second mixing tanks for mixing and supplying chemical slurries used in a semiconductor fabrication process. The slurries are alternately provided from the first and second mixing tanks such that the slurry is continuously available to a processing apparatus for maximum efficiency. While one of the tanks is supplying the slurry, the other tank is cleaned and then used to prepare a new batch of the slurry.
