  • Patent number: 8059257
    Abstract: An exposure apparatus includes a projection optical system configured to project light from an original, wherein the apparatus exposes a substrate to light through liquid filled in a gap between the last surface of the projection optical system and the substrate; and a detecting device configured to detect a droplet adhering to the exposed substrate. The detecting device includes a storage unit configured to prestore first image data corresponding to a surface of the substrate without the liquid and an image-capturing unit configured to capture an image of a surface of the exposed substrate. The detecting device detects the droplet based on a comparison between the first image data and second image data obtained by the image-capturing unit.

  • Patent number: 6833903
    Abstract: The object of this invention is to provide a technique of effectively purging a space almost closed with a master and pellicle film with inert gas in an exposure apparatus which uses ultraviolet rays as exposure light, purges the interior of the apparatus with inert gas, and projects the pattern of a master onto a photosensitive substrate via a projection optical system. To achieve this object, a plurality of vent holes are formed in a structure obtained by surrounding by a surrounding member a gas purge space to be purged with inert gas. A vessel which forms a space around the structure is filled with inert gas to cause inert gas to enter the gas purge space, purging the gas purge space with inert gas.

  • Patent number: 6803996
    Abstract: A reticle (23) with a pellicle is movably set on a reticle support table (28). An inert gas supply portion (29) and inert gas exhaust portion (37) are so driven as to sandwich a pellicle frame (25), and align the pellicle frame (25). The inert gas supply portion (29) and inert gas exhaust portion (37) are brought into tight contact with the pellicle frame (25). In this state, inert gas is supplied from the inert gas supply portion (29) into the pellicle space via a vent hole (27) of the pellicle frame (25). Inert gas is exhausted to the inert gas exhaust portion (37) via a vent hole (27) formed on the opposite side.
