Abstract:
In a chamber apparatus that includes a chamber and a target generation device configured to supply tin as a target material to a certain region in the chamber, oxidation of molten tin is prevented. A chamber apparatus includes: a chamber ( 1 ); a target generation device including a tank part ( 32 ) configured to store tin T, a variable temperature device ( 33, 38 ) configured to change a temperature of the tin T in the tank part ( 32 ), a pressure regulator ( 31 ) configured to change a pressure in the tank part ( 32 ), and a nozzle part ( 34 ) configured to eject liquefied tin T; a gas source ( 40 ) configured to supply gas containing hydrogen gas into the chamber ( 1 ); an evacuation device ( 46 ) configured to evacuate gaseous body in the chamber ( 1 ); and a controller ( 2 ) configured to control generation of a target, in which the controller ( 2 ) controls the evacuation device ( 46 ) to maintain an oxygen partial pressure in the chamber ( 1 ) at 4×10 −5  Pa or lower.

Claim (Index 1):
A chamber apparatus, comprising:\n a chamber; a target generation device assembled with the chamber, configured to supply tin as a target material to a certain region in the chamber, and including\n 1. a tank part configured to store tin, \n 2. a variable temperature device configured to change a temperature of the tin in the tank part, \n 3. a pressure regulator configured to change a pressure in the tank part, and \n 4. a nozzle part having a nozzle hole configured to eject liquefied tin; \n a gas source configured to supply gas containing hydrogen gas into the chamber; an evacuation device configured to evacuate gaseous body in the chamber; and a controller configured to control generation of a target and to control\n A. the evacuation device to maintain an oxygen partial pressure in the chamber at 4\u00d710 \u22125  Pa or lower, \n B. the variable temperature device to melt the tin, \n C. the pressure regulator to eject the molten tin from the nozzle hole, and \n D. the gas source to supply the gas containing hydrogen gas into the chamber after the ejection.
