Abstract:
1. An immersion exposure apparatus that projects a pattern of an original onto a substrate via a projection optical system and a liquid, thereby exposing the substrate, the apparatus comprising: a substrate stage mechanism including a substrate stage configured to hold the substrate; an immersion unit configured to supply the liquid into a space between the substrate or the substrate stage and the projection optical system, and to recover the liquid from above the substrate or the substrate stage; and a control unit configured to control said immersion unit to recover the liquid from above the substrate or the substrate stage, and then to control said substrate stage mechanism to move the substrate stage to a retreat position, in response to a shutoff request for requesting shutoff of electrical power supply to said substrate stage mechanism, wherein said control unit executes, in response to the shutoff request, a special process according to a process being executed by said immersion exposure apparatus when said control unit has received the shutoff request, and then controls said immersion unit to recover the liquid from above the substrate stage, and wherein if the process being executed by the immersion exposure apparatus when said control unit has received the shutoff request is an exposure process of continuously exposing a plurality of shot regions on the substrate, the special process includes ending the exposure process after waiting until the exposure of the shot region being exposed is completed.
