摘要： 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).

摘要： An exposure apparatus (EX) exposes a substrate (P) by irradiating exposure light (EL) on the substrate (P) through liquid (LQ). The exposure apparatus (EX) has a substrate holder (PH) for holding the substrate (P), a substrate stage (PST) capable of moving the substrate (P) held by the substrate holder (PH), and a temperature adjusting system (60) for adjusting the temperature of the substrate holder (PH). The temperature of the substrate (P) is controlled so that there is no difference in temperature between the substrate (P) and the liquid (LQ), thereby preventing a reduction in exposure accuracy resulting from variation in temperature of the liquid (LQ).
