    摘要: An apparatus and method for processing a substrate can reduce the concentration of process by-products in a chemical solution. The apparatus includes a substrate rotating device configured to rotate a seated substrate in a spinning manner, a chemical solution supply device configured to supply a chemical solution to the substrate, a chemical solution discharge line configured to discharge the chemical solution having undergone a process to an outside, a chemical solution circulation line configured to circulate the chemical solution having undergone the process to the chemical solution supply device, and a discharged chemical solution selection device configured to discharge a chemical solution containing a first amount of process by-products to the outside through the chemical solution discharge line and to circulate a chemical solution containing a second amount of process by-products through the chemical solution circulation line, wherein the first amount of process by-products is larger than the second amount of process by-products.
