    摘要: An apparatus and method for controlling temperature of a patterning device in a lithographic apparatus, by flowing gas across the patterning device. A patterning apparatus includes: a patterning device support structure configured to support a patterning device; a patterning device conditioning system including a first gas outlet configured to provide a gas flow over a surface of the patterning device and a second gas outlet configured to provide a gas flow over a part of a surface of the patterning device support structure not supporting the patterning device; and a control system configured to separately control the temperature of the gas exiting the first and second gas outlets such that the gas exiting the second gas outlet is at a higher temperature than the gas exiting the first gas outlet and/or to separately control the temperature and gas flow rate of the gas exiting the first and second gas outlets.

    摘要: An exposure apparatus (10) for transferring one or more features to a workpiece (22) includes an illumination source (44A); (ii) a chuck (40) that retains the workpiece (22); (iii) a chamber housing (28A) that encircles the chuck and the workpiece; and (iv) a temperature controller (32) (34) that adjusts the temperature of at least one of the chuck (40) and the workpiece (22) so that a predetermined temperature differential (309) exists between the chuck (40) and the workpiece (22) before transferring the features to the workpiece (22).

    摘要: An apparatus for generating at least one particle shield in photolithography includes a first component and a second component. The first component and the second component are operable to form a first particle shield of the at least one particle shield for blocking particles from contacting a proximate surface of an object. The first component includes a first gas injector, and the second component includes a first gas extractor corresponding to the first gas injector. The first gas injector is configured to blow out a gas, thereby forming the first particle shield. The first gas extractor is configured to work with the first gas injector for providing gas pressure gradient for the first particle shield.
