摘要 |
Exposure apparatus exposes a substrate by irradiating the substrate with exposure light via a projection optical system and a liquid. The exposure apparatus is provided with a liquid immersion mechanism for supplying the liquid and recovering the liquid. The liquid immersion mechanism has an inclined surface, which is opposite to a surface of the substrate and is inclined with respect to the surface of the substrate, and a liquid recovering port of the liquid immersion mechanism is formed in the inclined surface. A flat portion is provided between the substrate and the projection optical system. A liquid immersion area can be maintained to be small.
