US Patent 7495744 Exposure method, exposure apparatus, and method for producing device

When exposing a substrate by projecting a pattern image onto the substrate via a projection optical system (PL) and liquid (1), an exposure method includes a determination of a liquid immersion condition to be performed to the substrate, such as a liquid type, depending on a film (SP) formed as a liquid contact surface of the substrate. The liquid type is selected by switching between a first liquid supply section (11) and a third liquid supply section (21). It is possible to smoothly perform immersion exposure for the substrate (P) on which a different photo-resist layer is provided.
