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 4):
The chamber apparatus according to  claim 1 , wherein the controller performs the control A after the control B.
