Title:
特にリソグラフィのための極短紫外の光を生成するための方法及び装置
Document Type and Number:
Japanese Patent JP2004533704
Kind Code:
A
Abstract:
Method and device for generating light in the extreme ultraviolet, notably for lithography. According to the invention, a laser beam (24) is caused to interact with a dense fog (20) of microdroplets of a liquid. This liquid is a liquefied noble gas. In particular, liquid xenon (6) is used, the latter is produced by liquefying gaseous xenon (10) with which liquid xenon is pressurized to a pressure from 5x10<5 >Pa to 50x10<5 >Pa, and this liquid xenon is maintained at a temperature from -70° C. to -20° C., the pressurized liquid xenon is injected into a nozzle (4) the minimum internal diameter of which ranges from 60 mum to 600 mum, this nozzle opening into an area where pressure is equal to or less than 10<-1 >Pa.
