Title: Lithography system, device manufacturing method, device manufactured by the same
Inventor: MULKENS JOHANNES CATHARINUS H
IPC: G03F7/20
Filed: 2001-05-30
Abstract: PROBLEM TO BE SOLVED: To measure gas composition, such as oxygen level and water vapor level in a region where projection beam crosses, using a lithography projection system which uses an exposure radiation of 157 nm. SOLUTION: The irradiation amount of radiation accumulated during exposure, whose attenuation by the gas is anticipated as well as evenness and angular distribution of radiation energy which is applied to a board by the projection beam during exposure are controlled. The control includes controlling of supply amount of O2 to a volume where the projection beam crosses so that the projection beam is attenuated, while it is being controlled. The distribution of O2 may be uneven, for example, since a diffraction order which is spacially separated is selectively shielded, or unevenness of the projection beam is settled.
