    • An exposure apparatus includes a light source (34), an illumination optical system (36,37) for forming a secondary light source with light from the light source, and for illuminating a portion of a reticle having a pattern, a projection optical system (2) for projecting the pattern of the reticle as illuminated, on to a wafer, a reticle stage (1) for supporting the reticle and for scanningly moving the reticle in a predetermined scan direction, relatively to the projection optical system, a wafer stage (3) supporting the wafer and for scanningly moving the wafer relatively to the projection optical system, and a base (9) for supporting the reticle stage and being supported by dampers (11), wherein the illumination optical system is divided into a first portion (31) being supported by the base (9) and a second portion (32) supported by a floor, independently from the base, and wherein the predetermined direction of the reticle stage is substantially or approximately parallel to an optical axis direction at a location where the illumination optical system is divided.
    • 曝光设备包括:光源(34);照明光学系统(36,37),用于利用来自光源的光形成二次光源,并且用于照射具有图案的光罩的一部分;投影光学系统 2),用于将被照射的掩模母版的图案投影到晶片上;掩模母版台(1),用于支撑掩模母版并相对于投影光学系统在预定的扫描方向上扫描地移动掩模母版;晶片台 3)支撑晶片并相对于投影光学系统扫描移动晶片;以及底座(9),用于支撑光罩台并由阻尼器(11)支撑,其中照明光学系统被分成第一部分( 31)由所述基座(9)支撑,所述第二部分(32)由独立于所述基座的地板支撑,并且其中所述掩模版台的所述预定方向基本上或近似平行于光学器件 在照明光学系统被分割的位置处沿轴线方向。
