Patent ID: 7938129

Claim:
A substrate processing apparatus that applies processing using a processing liquid to a substrate, comprising: a first-side plate disposed oppositely to a first surface of the substrate with a distance and provided with plural discharge ports and suction ports in a surface opposing the first surface; a first-side processing liquid supply mechanism that supplies a processing liquid to the discharge ports in the first-side plate; a first-side suction mechanism that sucks insides of the suction ports in the first-side plate; a second-side plate disposed oppositely to a second surface of the substrate on an opposite side of the first surface with a distance and provided with plural discharge ports and suction ports in a surface opposing the second surface; a second-side processing liquid supply mechanism that supplies the processing liquid to the discharge ports in the second-side plate; a second-side suction mechanism that sucks insides of the suction ports in the second-side plate; and a second-side rotation driving mechanism that is coupled to the second-side plate and rotates the second-side plate about an axis line orthogonal to the surface of the second-side plate opposing the second surface of the substrate.
