Abstract
A substrate processing apparatus injects gas from an injection port formed on a shielding surface of an atmosphere shielding part and sucks a substrate by Bernoulli effect. The substrate is sucked in a state coming into contact with a contact supporting surface of a support member provided on the atmosphere shielding part, and rotated with the upper surface shielded by a shielding surface of the shielding part. A solution supply part supplies a chemical solution to the lower surface of the substrate. Therefore, mist of a processing solution or the processing solution can be reliably prevented from reaching the upper surface of the substrate. Thus provided is a substrate processing apparatus capable of reliably preventing the mist of the processing solution or the processing solution from reaching the upper surface of the substrate.
