A single-wafer-type cleaning apparatus is provided. The single-wafer-type cleaning apparatus is configured to be capable of controlling electrostatic charges generated due to rotating a wafer during a semiconductor cleaning process and a defect caused by the electrostatic charges. The cleaning process uses an ionizer mounted on a chuck.
