    摘要: An immersion lithography apparatus comprising a lens, formed from a liquid, which may be the immersion liquid located between the final element of the projection system and the substrate, and having optical properties that may be tuned by a tuning device. The tuning device is arranged to adjust properties of the liquid lens such as the shape, composition, refractive index or absorptivity as a function of space or time in order to change the imaging performance of the apparatus.

    摘要: An immersion lithography apparatus comprising a temperature controller (23) for adjusting the temperature of the final element of the projection system (PL), the substrate (W) and the liquid towards a common target temperature (T4). Controlling the overall temperature of these elements and reducing temperature gradients improves imaging consistency and general performance. Measures employed include controlling the immersion liquid flow rate and temperature via a feedback circuit.
