Abstract: An exposure apparatus exposes a substrate by irradiating exposure light on the substrate through liquid. The exposure apparatus has a substrate holder for holding the substrate, a substrate stage capable of moving the substrate held by the substrate holder, and a temperature adjusting system for adjusting the temperature of the substrate holder. The temperature of the substrate is controlled so that there is no difference in temperature between the substrate and the liquid, thereby preventing a reduction in exposure accuracy resulting from variation in temperature of the liquid.

Abstract: An immersion projection optical system having, for example, a catadioptric and off-axis structure, reduces the portion of an image space filled with liquid (immersion liquid). The projection optical system, which projects a reduced image of a first plane onto a second plane through the liquid, includes a refractive optical element (Lp) arranged nearest to the second plane. The refractive optical element includes a light emitting surface (Lpb) shaped to be substantially symmetric with respect to two axial directions (XY-axes) perpendicular to each other on the second plane. The light emitting surface has a central axis (Lpba) that substantially coincides with a central axis (40a) of a circle (40) corresponding to a circumference of a light entering surface (Lpa) of the refractive optical element. The central axis of the light emitting surface is decentered in one of the two axial directions (Y-axis) from an optical axis (AX).

Abstract: A catadioptric projection optical system includes a plurality of lenses which are arranged between a first plane on which the pattern is arranged and a second plane on which the substrate is arranged. Two mirrors are arranged in an optical path of the light beam between the plurality of lenses and the second plane. A dioptric optical system is arranged in an optical path of the light beam between the two mirrors and the second plane the dioptric optical system forming the image of the pattern onto the second plane by the light beam from the two mirrors. The dioptric optical system includes a first negative lens and a second negative lens, the second negative lens being adjacent to the first negative lens along the single optical axis.
