Abstract:
1. A substrate treatment apparatus, comprising: a spin-coating treatment chamber configured to coat a film on a substrate by spin-coating; a first air-conditioning mechanism configured to regulate an amount of dust in an air in said spin-coating treatment chamber; an annealing treatment chamber configured to perform lamp annealing treatment on said film coated on the substrate; a conveying chamber that is connected to each of said spin-coating treatment chamber and said annealing treatment chamber and is configured to convey the substrate between said spin-coating treatment chamber and said annealing treatment chamber; and a second air-conditioning mechanism configured to regulate an amount of dust in an air in said conveying chamber, wherein said spin-coating treatment chamber includes a rotation mechanism configured to rotate the substrate, a first nozzle configured to drop a chemical material onto the substrate rotated by the rotation mechanism, and a second nozzle configured to drop a cleaning liquid onto the film of the chemical material at an edge part of the substrate surface while dropping the chemical material onto the substrate by the first nozzle, wherein the first nozzle is configured to drop the chemical material while an excess of the film built-up at the edge of the substrate is removed by the cleaning liquid dropped by the second nozzle.
