TLDR
In this paper, an exposure device is used to fill a space between the final surface of a projection optical system and a substrate with a liquid in an immersion device to which an immersion method is applied.
Abstract
PROBLEM TO BE SOLVED: To surely fill a space between the final surface of a projection optical system and a substrate with a liquid in an exposure device to which an immersion method is applied SOLUTION: This exposure device comprises a liquid supply nozzle 5 disposed in the periphery of the projection optical system 4 and in the first direction as seen from the projecting optical system When a substrate 9 is moved in the second direction opposite to the first direction by a substrate stage 10, the liquid is supplied onto the surface of the substrate 9 through the liquid supply nozzle 5 to form a liquid film f on that surface Here, the liquid is continuously supplied onto the surface of the substrate 9 through the liquid supply nozzle 5 so that the liquid film f is continuously spread as the substrate 9 moves COPYRIGHT: (C)2005,JPO&NCIPI

Exposure apparatus, and device manufacturing method

TL;DR: In this paper, an exposure apparatus for emitting exposure light onto a substrate via a projection optical system and a liquid to expose the substrate includes a supply pipe which supplies the liquid, a recovery pipe which recovers the liquid; a connection pipe which connects the supply pipe and the recovery pipe; and a switching device which switches a flow path of the liquid so that when liquid supply is stopped, the liquid that has flowed into the input pipe flows to the output pipe via the connection pipe.
