SUBSTRATE PROCESSING APPARATUS AND SUBSTRATE PROCESSING METHOD

A substrate processing apparatus comprises a single-substrate processing apparatus for processing substrates one by one, and an anti-static liquid storage part for storing an anti-static liquid having electrical resistivity maintained at target electrical resistivity higher than the electrical resistivity of an SPM liquid. A plurality of substrates held in a cartridge are immersed in the anti-static liquid inside the anti-static liquid storage part and both main surfaces of the substrate entirely come into contact with the anti-static liquid. From the substrates, static electricity is relatively gently removed. Then, after the static elimination process are finished, a processing liquid supply part supplies the SPM liquid onto an upper surface of the substrate and an SPM process is thereby performed. It is thereby possible to prevent a large amount of electric charges from rapidly moving from the substrate to the SPM liquid and also possible to prevent any damage to the substrate.
