An exposure apparatus includes an illumination optical system configured to illuminate a reticle using extreme ultraviolet light, a projection optical system configured to project a pattern of the reticle onto a substrate, a diaphragm that defines a first space that accommodates the projection optical system, a first gas supplier configured to supply a first gas to the first space, and a first cooling unit configured to cool the first gas before the first gas supplier supplies the first gas to the first space.
摘要:
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.

An exposure apparatus includes a pellicle support frame which has a freely openable/closable lid and forms a pellicle space by using a pellicle film, and a pattern of a master facing the pellicle space is transferred onto a photosensitive substrate via a projection optical system. The apparatus includes a mechanism which opens/closes the lid, a nozzle arranged by selecting at least either one of a gas supply nozzle and a discharge nozzle, wherein at least either one of a gas supply and discharge is performed for the pellicle space via the selected nozzle, a device for measuring flexure of the pellicle film, a pressure detection device for detecting either one of a gas supply pressure and a discharge pressure, and a pressure control device for controlling the pressure detected by the pressure detection device. The pressure control device controls either one of the gas supply pressure and the discharge pressure so as to adjust a flexure value detected by the device for measuring flexure of the pellicle film to not more than a predetermined value.

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.
