    • An excimer laser generating system includes a laser chamber whose inner surface is covered with a fluorine-passivated surface. Preferably, the surfaces of a blower and heat exchanger disposed in the laser chamber are also covered with a fluorine-passivated surface. The fluorine-passivated surface may be formed of a wide variety of materials including an aluminum oxide film, a fluoride film containing aluminum fluoride and magnesium fluoride, iron fluoride, and nickel fluoride. Preferably, the excimer laser generation system includes a gas supply system having an inert gas purging system so that gas sources can be replaced without exposing the inside of gas supply pipes to atmosphere. With the above arrangement, the excimer laser generating system can generate a laser beam pulse whose energy and shape are maintained constant for a long period of operation time without encountering serious degradation. The invention also provides a high-reliability step-and-repeat exposure apparatus using the above excimer laser generating system, capable of exposing a very fine pattern.
    • 准分子激光发生系统包括其内表面被氟钝化表面覆盖的激光室。 优选地,设置在激光室中的鼓风机和热交换器的表面也被氟钝化表面覆盖。 氟钝化表面可以由各种各样的材料形成,包括氧化铝膜,含氟化铝和氟化镁的氟化物膜,氟化铁和氟化镍。 优选地,准分子​​激光发生系统包括具有惰性气体吹扫系统的气体供应系统,使得可以更换气体源而不将气体供应管的内部暴露于大气。 通过上述布置,准分子激光发生系统可以产生激光束脉冲,其能量和形状在长时间的操作时间内保持恒定,而不会严重恶化。 本发明还提供了使用上述准分子激光发生系统的能够曝光非常精细图案的高可靠性分步重复曝光装置。
