    摘要: An immersion lithography apparatus and method, and a lithographic optical column structure are disclosed for conducting immersion lithography with at least the projection optics of the optical system and the wafer in different fluids at the same pressure. In particular, an immersion lithography apparatus is provided in which a supercritical fluid is introduced about the wafer, and another fluid, e.g., an inert gas, is introduced to at least the projection optics of the optical system at the same pressure to alleviate the need for a special lens. In addition, the invention includes an immersion lithography apparatus including a chamber filled with a supercritical immersion fluid and enclosing a wafer to be exposed and at least a projection optic component of the optical system.
